New Features

Search Suggestions and Sorting

The web search box now suggests matching queries from search history, recent searches, aliases, fields, sort options, and facet values. Facet suggestions show result counts. The panel supports keyboard and pointer use, can be resized, and remembers its height.

A shared server schema keeps fields, facets, values, and sort options consistent across search clients. Queries can use sort:relevance, sort:date, sort:visits, or sort:domain. Prefix the value with a minus sign to reverse the order, as in sort:-date.

Social and Discussion Extractors

New Twitter, Bluesky, Reddit, and Discourse extractors preserve useful post, comment, reply, author, date, and reaction data. Twitter and Bluesky can split feeds and threads into separate post documents. Twitter also expands known shortened links to their original destinations.

Documents can now include JSON LD metadata. A new extractor SDK and registry define explicit results, capabilities, and optional context support.

Terminal Result Details

The terminal interface now has responsive workspaces and a readable result details pane. Wide terminals show the list and preview together. Narrow terminals use the full workspace. Text layout accounts for terminal cell width.

Local File Format Imports

hister import file can now import PDF, DOCX, Markdown, Org mode, valid UTF 8 text, and other supported local formats. It accepts individual files or directories. Extraction runs in the command line process and creates remote snapshots, so the server does not need access to the source files.

Service and Browser Imports

Hister can now import incrementally from Linkding, Readeck, and wallabag. Stored content is used when available, with a page download fallback. Browser imports can start at --start-date.

Bulk Document Updates

The new hister update command changes the owner, label, title, or language of documents matched by a search query. It supports dry runs, asks for confirmation, reports conflicts, and keeps file ownership rules intact.

Complete History Timeline

The history page now shows counts for all indexed or opened history. Recent days and older months are grouped for easier browsing, with daily details for a selected period.

Persistent Web Sessions

Web sessions are now stored in the configured SQL database. They survive server restarts, use rolling expiration, and are revoked at logout. Cookie security follows the configured server URL.

Structured MCP Results

The MCP endpoint now targets protocol version 2025-06-18 and defines output schemas for every tool. Results separate trusted metadata from untrusted source content, remove invisible control characters, and include safe handling guidance. Search callers can select full document fields.

Enhancements

1. Search interface: search duration is visible, index statistics are clickable, empty indexes show quick start help, errors are clearer, and recent searches are easier to identify and clear.
2. Query history: results promoted by query history are marked and can be forgotten for that query. Existing rules remain intact.
3. Command line: help now groups commands by scope. check-update reports new releases, and crawl urls can filter or count stored crawl URLs.
4. URL input: hister index --input accepts a file or standard input and creates a persistent job.
5. Files: watched directories can apply labels. Cleanup removes local documents that no longer match configured directories. File previews verify ownership and directory rules.
6. Batch imports: clients split batches at the configured request limit and report documents that are too large.
7. Browser extension: the extension supports access tokens and copied browser sessions. It refreshes changed cookies after authentication failures and submits pending page changes when a tab closes.
8. Web interface and docs: the header is more compact, the initial color scheme is configurable, accessibility is improved, and documentation now has search and clearer navigation.
9. Operations: profiling has an explicit setting. Container builds are smaller, and release images use Buildx Bake for supported architectures.
10. Crawler rendering: capture delay is shared by rendered backends and is now supported by Chromedp.
11. Terminal compatibility: command output and the TUI now use Charm v2, respect terminal color support, and preserve custom hotkeys.
12. Dependencies: Go modules, npm packages, Nix inputs, container bases, and GitHub Actions were updated.

Bug Fixes

1. Failed embedding jobs no longer starve later queued documents.
2. Index metadata access is safe during concurrent indexing.
3. Batch requests respect the server body limit and report oversized documents.
4. Field specific alternatives work correctly, and URL wildcard matching ignores letter case.
5. Browser imports count URLs correctly and handle empty history databases.
6. OAuth provider scopes are combined with default scopes.
7. Copied extension sessions use consistent expiry, and the background script works in browsers that require a classic script.
8. Sensitive content matches are no longer exposed in debug logs.
9. File indexing continues after an invalid symbolic link.
10. Opened history responses are decoded correctly.
11. Mastodon pages without a detected post are no longer stored.
12. Optional versioning rules remain optional, and prioritizing a result keeps the full rule set intact.
13. The middle pointer button still opens results while suggestions are visible.
14. Database conflict clauses now qualify column names correctly.
15. The configured color theme is applied before the page becomes visible.

Backward Compatibility Notes

The following changes require attention when upgrading from v0.17.0:

1. Login sessions: web users and extensions that copied a browser session must sign in once after upgrading. Access tokens are unchanged.
2. File preview API: /api/file now accepts a document id instead of an absolute path. Search and history results include this identifier.
3. MCP output: tool results now use schema version 1.0. Untrusted source values are under structuredContent.untrusted_content. Text output contains the same JSON and a security notice.
4. Extractor implementations: custom extractors must use the new SDK result constructors, capability declarations, and registry.
5. URL list input: hister index --url-list remains as a hidden deprecated alias. Use hister index --input; it also accepts - for standard input.

New Features

Unified Imports

The import interface is now grouped under hister import. In addition to local
files and browser history, Hister can import bookmarks and archived content from
Linkwarden, Karakeep, and Shaarli. Service imports preserve source dates and
metadata, apply source specific or overridden labels, fetch missing page content
and favicons, insert documents in batches, and continue from the latest imported
update after an interruption.

Persistent Crawl Job Tooling

Persistent indexing jobs can now start from URL lists, and browser history
imports use the same resumable crawl workflow. Jobs can be resumed with only a
job ID. New crawl show, crawl errors, and crawl queue commands expose job
state, failed URLs, queue contents, and queue counts.

Expanded Query Language and Search Filters

Documents now track an updated timestamp alongside their original added time.
Search queries support added and updated filters with relative or absolute
dates, visit count ranges, standalone wildcard expressions, and exact phrases
within specific fields. The search interface represents filters directly in the
query, making filtered searches easier to understand, edit, and share. Existing
index entries have their updated value backfilled from their added time on
startup.

Durable Semantic Indexing

Embedding work now uses a persistent queue and deduplicates pending documents.
Token measurement is more precise, requests reserve capacity below provider
limits, and batch size plus request timeout are configurable. Chunk construction
also uses document structure and more useful metadata.

Extensible File Types and DOCX Support

Local file handling now uses an extensible file type interface. DOCX documents
can be indexed with extracted text and metadata, and the documentation explains
the supported local formats and configuration.

Chinese, Japanese, and Korean Search

Language detection and language specific indexes now support Chinese, Japanese,
and Korean documents.

GitHub Issue and Pull Request Extraction

The GitHub extractor now understands issue and pull request pages. It indexes
the title, body, open date, comments, repository metadata, and useful page text.

Crawler Proxy Support

HTTP and SOCKS5 proxy URLs can now be configured for every crawler backend. The
new --proxy option also allows crawler backed index and import operations to
override the configured proxy, including robots.txt requests.

RFC Dataset

A new RFC dataset and fetch command make it easier to build a searchable local
collection of Internet standards.

Qutebrowser DevTools Companion

The new hister companion qutebrowser command connects to the Qt WebEngine
DevTools interface and indexes rendered tabs from qutebrowser. It accesses the
final document after client rendering without requiring a page userscript.

Enhancements

1. Search interface: sort choice is preserved in the URL, result index
   counts are visible, and the search input remains available while browsing
   results.
2. Semantic results: returned chunks are limited per document, metadata is
   richer, and index metadata is stored with the index itself.
3. Language aware indexing: indexer.keep_stopwords can retain common words
   while preserving language detection, normalization, and stemming.
4. Crawler efficiency: already skipped URLs no longer incur the configured
   crawl delay.
5. Import performance: imports use bulk insertion, retain useful imported
   titles and processed state, apply labels, and retrieve missing favicons.
6. Favicon delivery: favicons are served through a dedicated endpoint rather
   than being embedded in document responses.
7. Mastodon extraction: remote toot URLs are resolved to their canonical
   locations before indexing.
8. Command line workflow: search supports --sort, delete supports --yes,
   list files supports --relative, and command descriptions are clearer.
9. History: filtering now happens on the server and the selected filter is
   represented in the page URL.
10. Rules interface: multiple rules can be entered at once and rule lists use
    descending order by default.
11. Browser extension: pages may be submitted as public documents, Firefox
    mobile capability differences are handled, and automatic indexing accepts
    only HTML, XHTML, or plain text documents.
12. Website and documentation: the landing page, onboarding, navigation,
    accessibility, configuration reference, SEO metadata, and 404 page have been
    refreshed.
13. Operations: debug profile endpoints are available at debug log level, a
    sample systemd unit is included, and crawler failure codes are retained for
    inspection.
14. External tools: yt-dlp installation uses upstream releases and
    concurrent yt-dlp extraction is limited.
15. Dependencies: Go modules, npm packages, Nix inputs, GitHub Actions, and
    browser extension dependencies were updated.

Bug Fixes

1. SQLite semantic search uses cosine scoring consistently.
2. MCP search returns semantic results correctly.
3. Embedding requests avoid provider token limits and reduce batch size when a
   provider reports an oversized request.
4. Index resources are closed when initialization fails, absent documents are
   not deleted again, and document insertion avoids repeated lookups.
5. Startup only warns about reindexing for analyzer changes when analyzer
   configuration is present.
6. Stored previews reject meta refresh redirects.
7. Document domains no longer include ports, and invalid favicon schemes are
   ignored.
8. Public mode history is available to authenticated users and response headers
   are no longer written more than once.
9. Field specific phrase queries and a single wildcard query produce the
   expected matches.
10. Imports preserve existing titles when extraction finds no replacement, and
    the JSON input scanner accepts larger records.
11. The browser extension avoids unavailable command APIs on Firefox mobile and
    uses a compatible badge text color.
12. Search result and history titles and URLs retain usable space in narrow
    layouts.

Backward Compatibility Notes

The following changes require attention when upgrading from v0.16.0:

1. Import commands: hister import-browser has been replaced by
   hister import browser. File and directory imports now require the source
   subcommand, as in hister import file INPUT. Imported JSON exports retain
   their processed content without running extractors again. Browser imports now
   use persistent crawl jobs and can prompt to resume an unfinished job.
2. Date behavior: the structured date_from and date_to search parameters,
   facet date ranges, export date flags, date sorting, history ordering, and
   history RSS dates now use the document updated timestamp instead of
   added. The web interface no longer reads date_from or date_to from its
   page URL. Put added: or updated: expressions in the q parameter instead.
   For newly indexed local files, added is the indexing time and updated is
   the file modification time.
3. Favicon responses: search and history results return favicon_key instead
   of embedding stored favicon data. API clients should fetch the image from
   /api/favicon?key=FAVICON_KEY. Legacy inline favicon values remain readable.
4. Domain normalization: newly indexed and reindexed documents store only the
   hostname in domain, without the port. Queries and integrations that expect a
   host and port value must be adjusted.
5. Semantic search: SQLite vector stores migrate from Euclidean distance to
   cosine distance. Custom similarity_threshold values may need adjustment.
   When omitted from configuration, the default context length changes from
   4096 to 512, chunk overlap from 128 to 64, and embedding concurrency from 10
   to 2.
6. Browser extension submissions: the extension no longer submits images,
   videos, or other unsupported document types. This content type restriction
   also applies to manual submission.

New Features

Public Search Mode

Hister can now run in public mode, allowing unauthenticated read-only access to
global search results and previews while keeping write operations protected.
This makes it possible to publish a shared or community search instance without
exposing private user data. Public mode is documented across configuration,
server setup, user handling, and the new public search blog post.

Documentation Datasets

Hister now ships dataset metadata and tooling for importing common reference
documentation. New datasets cover Go standard library, PowerShell, Python, Rust,
Node.js, and refreshed MDN datasets. Compressed dataset imports are supported, so
pre-built documentation archives can be imported directly.

StackExchange Extractor

The StackOverflow extractor has been replaced by a generic StackExchange
extractor. It supports StackExchange-style question pages more broadly and
indexes answers with useful metadata.

Markdown and Org Mode Extractors

Local Markdown and Org files now render as HTML previews. Markdown titles are
extracted automatically, Markdown syntax is stripped from indexed text, and Org
files are rendered through go-org for cleaner previews.

MCP History and Capability Reporting

The MCP endpoint now exposes a get_history tool for recently indexed pages and
opened search result history. MCP search supports date filters, and MCP clients
can discover whether semantic search is enabled on the current Hister instance.
The MCP documentation and examples have been expanded accordingly.

Browser Extension Hotkeys and Indexing Indicators

The browser extension now includes configurable commands to manually index the
current page, disable indexing for the current page, and disable indexing for
the current domain. Badge feedback indicates success or failure. The extension
can also show whether the current page has already been indexed, with a popup
setting to control the indicator.

Import and Export Improvements

Imports now support HTML files, multiple input files in a single command,
compressed JSON archives, directory imports for supported local file types, and
optional user IDs. Import and export commands can be limited by date range.
Browser history import gained a redesigned interactive flow and a --backend
flag for selecting the scraping backend.

Search JSON Output

The /search endpoint now supports format=json, making it easier to integrate
Hister search results with scripts and external tools.

Search Sorting

Search results can now be sorted by newest date, domain, and most visited pages.
Documents track an add_count field that records how many times a URL has been
indexed, and the web UI exposes this as the "Most visited" sort mode.

History RSS Feed

The history endpoint and history UI now expose an RSS feed for recently indexed
documents.

Enhancements

• File indexing startup: initial file indexing now runs in the background so
  server startup is not blocked by watched directory indexing (closes #499)
• Directory indexing queue: watched directory indexing uses a proper queue,
  logs queue errors, and avoids duplicating file indexing logic
• Sensitive content override: CLI indexing can explicitly allow sensitive
  content when requested
• Semantic search: embedding generation has a concurrency limit, semantic
  result counts are more accurate, and shared plus user-specific vector results
  are merged
• History view: the history timeline has been redesigned, supports loading
  more items, shows when a day has unloaded items, and displays indexed version
  counts
• Search UI: the results layout, home layout, dark theme, add entry form,
  search input, and shared chrome have been refined
• Facets: type facets were added, inactive facet categories are hidden when
  they only have one candidate, and facet rendering was refactored
• Preview and history integration: history supports diff previews for
  versioned documents, preview links are proper anchors, and previously opened
  results stay visible after unpinning
• Configurable branding: the web UI title and subtitle can now be configured
• Logging: log output format and log file path are configurable, and panic
  stack traces are available in debug logs
• Environment variables: environment variable overrides now preserve typed
  values instead of treating everything as a string
• Terminal UI: the TUI package now lives under cmd/tui, includes updated
  command documentation, and supports result sorting
• CLI structure: the command line implementation was split into a dedicated
  cmd package for easier maintenance
• Docker image: yt-dlp is now installed in the Docker image
• Dependencies: Go, npm, GitHub Actions, Nix, GORM, SQLite, and PDF related
  dependencies were updated

Bug Fixes

• Lobsters extraction works with the updated Lobsters HTML structure
• Document labels are added and preserved correctly
• Opened history filtering and history list layout no longer squeeze content
• Result text wraps correctly in the web UI
• Description lines no longer force table scrolling
• Base URL handling is more consistent for app URLs, CSRF checks, and invalid
  base URL values
• The preview panel is cleared when a search returns no results
• Reindexing no longer stops when an extractor aborts one document
• Lazy loading works when the previous page returned fewer than the configured
  page size
• Database migrations no longer unintentionally update UpdatedAt
• PDF parsing panics are recovered, and PDF dependency updates address memory
  issues
• Versioned document diffs use the newly stored document when calculating
  changes
• Batch operations handle user IDs correctly
• Extra documents no longer increment the parent document add count
• Subtitle rendering is centered correctly
• Python dataset generation fetches only standard library documentation
• Nix paths and hashes were updated after Go and npm dependency changes

• History view: the history timeline has been redesigned, supports loading more items, shows when a day has unloaded items, and displays indexed version counts
• Search UI: the results layout, home layout, dark theme, add entry form, search input, and shared chrome have been refined
• Facets: type facets were added, inactive facet categories are hidden when they only have one candidate, and facet rendering was refactored
• Preview and history integration: history supports diff previews for versioned documents, preview links are proper anchors, and previously opened results stay visible after unpinning
• Configurable branding: the web UI title and subtitle can now be configured
• Logging: log output format and log file path are configurable, and panic stack traces are available in debug logs
• Environment variables: environment variable overrides now preserve typed values instead of treating everything as a string
• Terminal UI: the TUI package now lives under cmd/tui, includes updated command documentation, and supports result sorting
• CLI structure: the command line implementation was split into a dedicated cmd package for easier maintenance
• Docker image: yt-dlp is now installed in the Docker image
• Dependencies: Go, npm, GitHub Actions, Nix, GORM, SQLite, and PDF related dependencies were updated

Bug Fixes

• Python dataset generation fetches only standard library documentation
• Nix paths and hashes were updated after Go and npm dependency changes

New Features

Document Versioning

A new versioning rule type instructs Hister to track changes to a document each
time it is re-indexed. A diff-style changelog appears inside the preview panel so
you can see what changed between versions, and the preview endpoint returns the
full version history. Combine with a priority or skip rule to version only the
pages that matter to you.

Priority Rules

Priority rules have been reintroduced (closes #222). Documents whose URLs match a
priority rule are pinned to the top of search results regardless of their relevance
score. Rules can be created, edited, and sorted directly in the web UI.

PDF Indexing

Local PDF files can now be indexed with full text extraction. The browser extension
gains a new endpoint for sending PDFs directly to the server (closes #55). Indexed
PDFs are stored as a distinct document type and can be filtered with
metadata.type:pdf in search queries.

Faceted Filtering

Search results can now be filtered through facets that group documents by common
fields such as language, and domain. Facet counts update live as you refine your
query. Date-range filters have been moved into the same filters dropdown for a
unified experience, and a "load more" control expands facets with many values.

Embedded Video Extractor

A new extractor detects embedded videos (YouTube, Vimeo, and similar platforms)
on indexed pages and stores the embedding metadata as a dedicated document type.
Embedded videos are rendered directly inside the result preview panel, so you can
watch them without leaving Hister (closes #446).

Notion Extractor

A dedicated extractor for Notion pages extracts article content cleanly from
public Notion URLs, removing navigation chrome and other non-content elements.

Compressed HTML and Favicon Storage

HTML content and favicons are now stored gzip-compressed in separate files on
disk rather than inline inside the Bleve index. This significantly reduces index
size on disk and lowers memory pressure during search (closes #384).

Disable HTML Storage

A new config option lets you turn off full HTML storage and preview generation
entirely. Disabling storage trades preview functionality for a smaller footprint,
useful for bulk or headless indexing workflows (closes #440).

User-Specific Directory Indexing

The indexer.directories config now accepts a user field per directory entry.
Files under that path are indexed only for the specified user, making it easy to
share a single Hister instance while keeping personal file indexes private.

Label Editing from Results

Document labels can be edited inline directly from search result cards without
navigating away. The browser extension can also apply a one-off label to a
document at index time (closes #407). Updating a document no longer clears
previously assigned labels.

File Deletion Tracking

When a locally-watched file is deleted from the filesystem, Hister now
automatically removes it from the index (closes #230). Batch and single-document
deletions also clean up the associated HTML and favicon files from disk.

MCP Document Preview Endpoint

A new MCP endpoint exposes document previews to LLM agents and MCP-compatible
tools, complementing the existing MCP search endpoint.

Browser Import: Ladybird Support

The import-browser command now supports importing history from the
Ladybird browser.

Browser Import: Auto-Detect Database

The import-browser command now automatically detects the browser database file
path, so passing an explicit path is no longer required for supported browsers.

Enhancements

• Copy URL button: a copy-to-clipboard icon appears next to each result URL
• Preview extractor selector: switch between available extractors when viewing
  a document preview without re-indexing
• Rules table: columns are sortable; values are filterable; filter toggle
  buttons are visually distinct from column headers; regexp validation runs before
  saving a rule
• CLI index flags: --delay, --timeout, and --user-agent are now
  available directly on hister index without needing a config file
• Configurable client timeout: the HTTP client timeout used during indexing
  is configurable (fixes #429)
• Standardized config file lookup: config file discovery follows a consistent
  search order across all platforms (closes #424)
• History autoscroll: the history view scrolls to keep the selected entry
  visible (#427)
• Admin profile version: the admin profile page now shows the running Hister
  version (closes #409)
• Log level aliases: common short aliases are accepted for log level values
  (fixes #411)
• Random tips: a rotating set of usage tips is shown on the front page when
  navigating back from search results
• yt-dlp diagnostics: clearer error messages and debug logging help diagnose
  yt-dlp configuration problems
• Batch crawl insertion: URLs discovered during a recursive crawl are
  inserted in batches for better throughput
• Extension popup header: the popup header is now a link to the configured
  Hister server
• Per-sub-index paging: each language sub-index is iterated independently to
  prevent paging gaps in multi-language setups
• Improved embedding handling: fallow and embedding request processing
  is more robust

Bug Fixes

• Docker BASE_URL environment variable can now be correctly overridden by a
  config file (closes #442)
• Search results now contain all queried terms rather than any of them
• HTML is no longer re-written to the indexer during a reindex run
• yt-dlp subtitle download no longer skipped when the sub language differs from
  the original language (#429)
• History page stops loading more entries when the last page has been reached
• "Show all" in history now scrolls back to the top
• Rule type filter no longer incorrectly excludes rules
• Debug-level init messages are correctly suppressed at higher log levels
• Result paging uses a valid sort key, fixing out-of-order pages
• Times are displayed in the browser's configured timezone

WARNING

If you are using Hister with a custom config file under Docker, make sure you have the listen address set to 0.0.0.0:4433 in your config file.

New Features

Mastodon Extractor

A dedicated extractor for Mastodon detects Mastodon pages and indexes each
toot as its own separate document rather than one big blob of text. Works
with any Mastodon instance without configuration. Every toot gets a
metadata.type:toot field so you can filter toots in search queries.
Combined with a search alias (!toot → metadata.type:toot) this makes
finding past toots fast and convenient.

Metadata Query Filtering

Documents can now be filtered by arbitrary metadata fields using the
metadata.key:value query syntax. Extractors (including the newMastodon
extractor) populate these fields at index time.

Full Screen Preview

The split-screen preview can now be toggled into a full-screen mode that
occupies the entire content area (closes #401). The URL changes to
/preview/[id] so the view survives a page reload. Pressing the "view
result content" hotkey switches between split and full-screen. Full-screen
preview is also available on the history page.

Preview Panel on History Page

The history page now shows the same interactive preview panel as the search
page (closes #395). Hotkey navigation between history entries works the same
way as on the search page.

Infinite Scroll

Search results now load more pages automatically as you scroll to the bottom
of the list, removing the need to manually page through results (closes #1).

Image Lightbox

Images displayed inside the preview panel can be clicked to open a full-size
lightbox view.

Delete All Results

A new "delete all" action removes every document that matches the current
search query at once, without having to delete results one by one.

Keyboard Shortcut for Result Deletion

A dedicated hotkey deletes the currently focused search result directly from
the keyboard.

Quick Skip Rule

A skip-rule component lets you add a URL to your skip list directly from a
search result, available in both the web app and the browser extension
(closes #380).

robots.txt Support

The crawler and hister index now respect robots.txt by default (closes
#386). A new ignore_robots_txt config option disables this check when
needed.

Document Labeling

Documents can be tagged with custom labels when indexing from the CLI
(--label) or from the browser extension. Labels are stored as metadata
and can be used in search queries (closes #156, #373).

Editable Rules and Aliases

Existing skip/priority rules and search aliases can now be edited in the
web UI instead of having to delete and recreate them (closes #270).

Exact Phrase Matching

Multi-word queries now also attempt an exact phrase match across title and
text, so searching for open source surfaces pages that contain that exact
phrase more prominently (closes #394).

Extractor Templates and Extra Document Creation

Extractors can now supply a custom preview template, giving each content
type its own presentation in the preview panel. Extractors can also produce
additional sub-documents from a single page (used by the Mastodon extractor
to create one document per toot). A template scaffold is included to make
writing new extractors easier.

WebDriver BiDi Crawler Backend

A new bidi crawler backend uses the W3C WebDriver BiDi
protocol to drive an already-running browser over a WebSocket connection.
Unlike the chromedp backend, it does not launch a browser process: you start
the browser yourself (headless or not) and point Hister at it:

# Firefox
firefox --remote-debugging-port 9222

# Chrome / Chromium
chromium --remote-debugging-port=9222

crawler:
  backend: bidi
  backend_options:
    host: '127.0.0.1'
    port: '9222'
    capture_delay: 1.5 # extra seconds to wait after load for JS rendering

Supported by Firefox (≥ 102), Chrome/Chromium (≥ 106), and Edge. Options:
socket (full WebSocket URL), host, port, capture_delay. The crawler
reuses a single BiDi session for all URLs in one hister index run, making
multi-URL indexing significantly more efficient than opening a new browser
session per URL (closes #284).

Enhancements

• Resizable preview panel: drag the divider in split-screen view to
  adjust the panel width; the chosen width persists across sessions
• History hotkey navigation: keyboard navigation between history entries
  on the history page
• Secondary date sorting: when search scores are equal, results are
  sorted by indexed date
• yt-dlp multi-language subtitles: configure which subtitle languages
  the yt-dlp extractor indexes
• MCP date filtering: MCP search requests can now be filtered by date
• Semantic search chunking: punctuation-based boundaries used for
  chunk splitting, improving relevance for sentence-level queries
• OIDC enhancements: userinfo endpoint is now configurable for
  providers without auto-discovery (#279); password login can be disabled
  when OAuth is the only configured auth method
• Clearer CLI error messages: client-side HTTP errors now explain the
  problem in plain words and suggest which flag to use (#400)
• Duplicate rule prevention: the server and UI both reject duplicate
  skip/priority rules and aliases (#399)
• Deletion error feedback: errors during document deletion are now
  surfaced in the UI
• Rules/aliases UX: input fields moved above their respective lists
• Version string in server log: the server start message now includes
  the version number (#372)
• Silent WebSocket disconnect: closing the browser tab no longer shows
  a connection-error message

Bug Fixes

• Search terms are now properly escaped before query execution
• Focused result index computed correctly when priority results are present
• Phrase queries are only applied when no field-specific terms exist in the
  query
• /api/delete requests from the browser extension are now accepted
• text and html fields always included in search results (#374)
• Language field included in document search results
• OIDC scopes correctly forwarded to the provider (#371)
• Auth page is scrollable on small screens (#370)
• TUI client now passes the access token to the server (#368)
• Optional peer dependencies no longer excluded on non-Linux platforms (#299)

• Optional peer dependencies no longer excluded on non-Linux platforms (#299)

New Features

Semantic Search

Full vector search support via sentence-embedding models. Documents are chunked
and embedded at index time; search queries are embedded at query time and ranked
by cosine similarity. Two storage backends are supported:

• SQLite (default, via bundled sqlite-vec) zero extra infrastructure required
• PostgreSQL with pgvector auto-selected when the database is Postgres

Configure the embedding API endpoint, model, dimensions, and chunking parameters
in the new semantic config section. Semantic search is opt-in and off by default.
Relevance scores are shown alongside results when semantic search is active.

OAuth / SSO Authentication

OAuth 2.0 and OpenID Connect (OIDC) providers can now be configured as login
methods. Add one or more entries to the new server.oauth config section with
client_id, client_secret, configuration_url (for OIDC auto-discovery), or
manual auth_url / token_url, and optional scopes. Multiple providers can be
active at the same time alongside the built-in username/password login.

MCP Server

Hister now exposes a Model Context Protocol
endpoint at /api/mcp, enabling LLM agents and MCP-compatible tools to search
the index directly.

Persistent Crawler State Management

Recursive crawl jobs (hister index -r) are now stored in the database and
survive interruptions. Each job gets a unique ID (auto-generated or set via
--job-id). Pass --job-id <id> without --recursive to resume an
interrupted crawl from exactly where it left off, including original validator
rules and visited-URL counts.

New Extractors

• Wikipedia extracts the article body and infobox, rewrites relative links, and sanitizes the output
• GitHub project extracts repository descriptions and README content from GitHub project pages
• Lobste.rs dedicated extractor for Lobste.rs story and comment pages
• yt-dlp extracts video metadata (title, description, channel) from video pages via yt-dlp
• JSON-LD surfaces structured metadata (@type, headline, description) from pages that embed JSON-LD

All extractors now expose a Description() method, and an extractor information
page is available at /extractors in the web UI.

OpenSearch Suggestions

The server now serves an OpenSearch suggestions endpoint (/api/suggest),
allowing browsers to display search-as-you-type completions when Hister is
configured as a search engine.

Enhancements

Crawler Backend for All Index Operations

The --backend flag (and --backend-option) is now available on both
hister index (plain and --recursive) and hister import-browser, allowing
a headless Chrome/Chromium backend for JavaScript-heavy pages without running a
full recursive crawl:

hister index --backend chromedp https://example.com
hister import-browser --backend chromedp --backend-option exec_path=/usr/bin/chromium

Headers and cookies can also be injected per-invocation:

hister index --header "Accept-Language=en" --cookie "session=abc; Domain=example.com" https://example.com

Cookies use standard Set-Cookie format with a required Domain attribute.

CLI Search Improvements

• --limit N flag caps the number of results returned
• --fields flag selects which document fields to include in output
• --html flag includes raw HTML content in the output
• Paging support added to both CLI search and list-urls
• list-urls now fetches results from the server by default; --offline connects directly to the index without a running server

Quoted Field Queries

Field-qualified queries now support quoted values, enabling correct deletion and
lookup of URLs that contain spaces (common on Windows file paths):

url:"file:///C:/Users/My Documents/notes.txt"

Preview Panel Polish

• Preview title is now clickable (opens the result URL)
• Preview panel maximises available content width
• JSON-LD metadata surfaced inside the preview panel
• Dark theme font colors fixed in preview popup

NixOS / Nix Module

• systemd and launchd hardening applied to the Hister service units
• New services.hister.environmentFile option for secrets injection
• openFirewall now requires explicit opt-in
• services.hister.config renamed to services.hister.settings

Other

• Version information included in the MCP endpoint response
• Timezone data bundled into the binary for environments without a system tzdata

Bug Fixes

• File URLs (file://) now handled correctly in the UI for both opening and deletion (#362)
• Browser extension authentication documentation corrected (#366)
• URLs no longer lowercased during query building, preventing mismatches on case-sensitive paths
• History view correctly filtered per-user in multi-user mode (#314)
• Token authentication middleware now respects NoAuth flag (#348)
• Documents with no HTML content no longer attempt HTML extraction (#351)
• Extension no longer resubmits documents after a 406 Not Acceptable response
• Priority results correctly deduplicated against standard results
• File indexing fixed on Windows
• Wide tables no longer overflow the preview panel
• Score field populated correctly in search responses

• --fields flag selects which document fields to include in output
• --html flag includes raw HTML content in the output
• Paging support added to both CLI search and list-urls
• list-urls now fetches results from the server by default; --offline connects directly to the index without a running server

Quoted Field Queries

Field-qualified queries now support quoted values, enabling correct deletion and lookup of URLs that contain spaces (common on Windows file paths):

url:"file:///C:/Users/My Documents/notes.txt"

Preview Panel Polish

• Preview title is now clickable (opens the result URL)
• Preview panel maximises available content width
• JSON-LD metadata surfaced inside the preview panel
• Dark theme font colors fixed in preview popup

NixOS / Nix Module

• systemd and launchd hardening applied to the Hister service units
• New services.hister.environmentFile option for secrets injection
• openFirewall now requires explicit opt-in
• services.hister.config renamed to services.hister.settings

Other

• Executable size reduced ~70 MB by switching to a trimmed lingua-go fork
• Sensitive content rejection errors surfaced in the browser extension
• --verbose flag on hister delete lists matched URLs before deleting
• Priority result deduplication now copies body text from the original result
• /suggest endpoint protected by auth middleware and Sec-Fetch-Site header check
• Version information included in the MCP endpoint response
• Timezone data bundled into the binary for environments without a system tzdata

Bug Fixes

• File URLs (file://) now handled correctly in the UI for both opening and deletion (#362)
• Browser extension authentication documentation corrected (#366)
• URLs no longer lowercased during query building, preventing mismatches on case-sensitive paths
• History view correctly filtered per-user in multi-user mode (#314)
• Token authentication middleware now respects NoAuth flag (#348)
• Documents with no HTML content no longer attempt HTML extraction (#351)
• Extension no longer resubmits documents after a 406 Not Acceptable response
• Priority results correctly deduplicated against standard results
• File indexing fixed on Windows
• Wide tables no longer overflow the preview panel
• Score field populated correctly in search responses
• aws_access_key sensitive content pattern tightened to reduce false positives
• Home-manager service units correctly gated on host platform in Nix module

New Features

Web Crawler

New hister index -r <url> command crawls sites recursively.
Supports the standard Go HTTP backend and a headless Chrome backend (chromedp).
Configurable depth, link count, allowed/excluded domains, and URL patterns.

PostgreSQL Backend

Full PostgreSQL support as an alternative to SQLite.
Configure via a postgres:// connection string in server.database.

Extractor Pipeline Overhaul

Extractors are now configurable, have explicit states (continue/done), and expose
a Preview() method used by the preview panel. New extractors included:

• Custom pkg.go.dev extractor for Go documentation pages
• Basic Stack Overflow extractor

Desktop Readability Panel

Focused search results load automatically in a split-pane reader on the right side
on screens wider than 1280 px. The panel is togglable and its open/closed state persists.

Enhancements

• HTML sanitizer (bluemonday) applied to all extracted content
• metadata field added to documents for arbitrary key/value data
• search input type attribute on search fields for better mobile UX
• Build commit ID shown in the version string
• Admin users can create global indexes or indexes on behalf of other users
• hister index skips already-indexed URLs by default; pass --force to reindex them
• URL and domain wildcard matching automatically anchors to start and end
• Table of contents added to the API docs page
• Document indexed date shown in the preview panel
• Search query reflected in the browser tab title
• WebSocket communication optimised to reduce redundant round-trips
• Automatic redirect on zero results is now optional (configurable)
• import command renamed to import-browser to free import for index import/export

Bug Fixes

• Browser history database opened read-only to avoid lock conflicts (#304)
• History entries now deleted when their associated document is deleted (#303)
• Crawler user-agent correctly applied after redirect handling (#302)
• Fixed field-specific alternation parts in query parser (#274)
• Negated query terms no longer trimmed twice
• HTML field no longer leaks into search results (#268)
• Expanded query hint only shown when the expansion is longer than the original query
• URL changes after HTTP redirects now resolved correctly
• Crawler no longer stops on HTTP errors
• Crawler timeout now applied during browser history import (#278)
• Pinned result titles no longer truncated on narrow screens
• Dark mode handled correctly in the preview panel
• Mobile layout no longer introduces unwanted line breaks
