Opensolr Changelog — Recent Updates & Improvements

Drupal Apr 22, 2026

New Opensolr Search for Drupal 3.5.0 — adds the Lexical Only search mode, matching the option in the Opensolr admin. Skips the embedding request entirely and runs pure lexical search. When selected, the Minimum Relevance Score is auto-zeroed (on save and at query time) so results aren't filtered out by a hybrid-calibrated threshold. Same feature across the stack — Opensolr admin, Drupal module, WordPress plugin.

New Opensolr Search for Drupal 3.4.0 — adds the Minimum Relevance Score slider to Search Tuning, matching the feature in the Opensolr admin. Drops low-scoring hybrid hits from results and facet counts. Slider is in 0.1 increments, default 0.3. Includes an update hook that restores the setting for sites upgrading from older versions.

Fix Fixed Drupal module Save & Connect not registering the sitemap URL with the crawler. The sitemap is now registered on every Save & Connect and Save & Start Fresh. Also fixed Save & Start Fresh not deleting the previous index before creating a new one. Released as 3.3.3.

Fix Fixed Query Elevation REMOVE button appearing on results with no elevation rules. Visibility now controlled via CSS class specificity instead of inline styles, fixing conflicts between button display and hide states.

New Drupal Module Partner Program — get 50% off any small or medium plan for a full year by installing and actively using the free Opensolr Search Drupal module. Provide feedback, suggestions, or bug reports in exchange. Apply from the pricing page.
Fix Safari and iOS compatibility — fixed show-more buttons, async noUiSlider loading, expand dialog z-index above Drupal toolbar, mobile overflow handling. Show-more dialogs now use event delegation for reliable touch behavior.
Improved Per-facet minimum count threshold — configure how many documents a facet value needs before it appears. Instant CSS tooltips on facet hover replace slow browser title popups. Facet values preserve original casing from the source data.
New Hierarchical drill-down facets — navigate multi-level taxonomies like breadcrumbs (e.g. Products > Electrical testing > Clamp meters). Auto-detected from JSON-LD BreadcrumbList data. Supports starting from any level and "Show more" for large lists.

Improved Language selector dropdown now shows the active language first instead of alphabetical order. Crawler Settings section moved above Content Types for better admin UX.
Improved Data Crawler and Data Ingestion admin tabs now show live document counts next to each content type — checked types show the real count, unchecked show 0, with a running total that updates instantly as you toggle checkboxes.
Improved Opensolr Search for Drupal — full multilingual support for meta tags and JSON-LD structured data. Product categories, tags, and brands now output in the correct page language, so the Web Crawler extracts translated facet values identical to Data Ingestion.

Improved Opensolr Search for Drupal — added Stop Crawl button, price display with currency symbols, and optimized query embeddings for better search relevance.

Improved Contextual help links across all 10 admin tabs — descriptions and labels now link directly to relevant documentation and learn pages for hybrid search, autocomplete, facets, elevation, and more.
New Opensolr Search for Drupal 2.0 released — major update with Data Ingestion API, real-time sync on every node save/delete, async bulk ingestion via Drupal cron (scales to 500K+ documents), full CJK/UTF-8 safety, and a 3-round security audit. Full documentation.

New Opensolr Search — official Drupal module now available on Drupal.org. Adds hybrid vector + keyword search, faceted navigation, autocomplete, AI Hints, AI Reader, spellcheck, Query Elevation, built-in analytics dashboard, and a sitemap generator — all powered by the Web Crawler. No dependency on Search API. Works with Drupal 10 and 11.
