Opensolr Changelog — Recent Updates & Improvements

Drupal Module Apr 24, 2026

Fix Drupal Facet Mapping Saves Apply Instantly via Render Cache Tag Invalidation
Saving a new Facet Mapping now takes effect immediately — no drush cr required. Render cache tags are invalidated on save so every cached node and commerce product page re-renders with the newly-mapped opensolr:* meta tags on next view.

WordPress Plugin Apr 24, 2026

Fix WordPress Plugin Fix: Sanitize Callback No Longer Strips Saved Facet Mappings
Facet Mapping saves persist correctly. A legacy sanitize callback in the WordPress plugin was silently stripping every saved row under the sanitize_option_opensolr_settings filter — saves looked successful but the data never made it to the database. Fixed: the callback now handles the new rich mapping shape AND auto-promotes any legacy rows on first save.

Facet Mapping Apr 24, 2026

Fix Image and File Facet Mappings Now Emit Real URLs Instead of Attachment IDs
Image and File field mappings now emit a real URL instead of the bare attachment ID. Mapping a Drupal field_image or a WordPress meta that stores an attachment ID (ACF image field with Return Format = ID, _thumbnail_id, custom image_attachment_id) now resolves to a working public URL. Guarded against numeric SKU/price fields being silently rewritten.
Fix Multi-Valued Facet Mappings Fixed: Crawler and Ingestion Now Produce Identical Documents
Multi-valued field mappings work correctly end-to-end. Drupal taxonomy terms, ACF Checkbox/Select-multiple/Relationship/Gallery arrays, and WooCommerce attributes (all stored differently — multi-row vs serialized-array) now all emit as one <meta property="opensolr:X_sm"> tag per value. The Web Crawler aggregates repeated tags into a Solr array, matching what real-time ingestion already writes — so crawler and ingestion produce identical documents.
New Facet Mapping: All WordPress Post Columns, Postmeta Keys and WooCommerce Taxonomies Mappable
Every indexable WordPress source is now mappable — core post columns (post_title, post_content, post_excerpt, post_date, post_author, …), ALL postmeta keys (the underscore-prefixed WooCommerce core fields like _price, _sku, _stock, _thumbnail_id are now visible — previously hidden as "private"), every public taxonomy, all WooCommerce pa_* attribute taxonomies, plus synthetic featured_image_url and gallery_image_urls aggregates.
Improved Facet Mapping Auto-Detects Solr Field Types on Drupal and WordPress
Facet Mapping got a big UX upgrade on both platforms. Pick a Drupal/WordPress field and the Solr Type dropdown auto-fills with the detected suffix — _s for a plain string field, _sm for a multi-valued taxonomy, _f for a WooCommerce price, _dt for a date field. Every entry in the field dropdown shows its detected type inline (post_tag — multi, string; _price — single, float) so you know before you click.

Drupal Module Apr 24, 2026

New Opensolr Search Drupal Module 3.8.0: Thumbnails, Facet Mapping and Multi-Valued Fields
Opensolr Search Drupal module 3.8.0 tagged on drupal.org — first public release since 3.6.0. Configurable result thumbnail field, auto-suggesting Facet Mapping form, full multi-valued field pipeline (crawler + ingestion + meta tags).

WordPress Plugin Apr 24, 2026

New Opensolr Search WordPress Plugin 1.0.19: Facet Mapping Overhaul and Stability Fixes
Opensolr Search WordPress plugin 1.0.19 is live on WordPress.org — admins will see the update prompt within 15 minutes of publication. Major Facet Mapping overhaul, plus every fix from the last two weeks rolled into one stable release.

Search Apr 22, 2026

Fix Search Page Fix: showPicker SecurityError in Cross-Origin Iframes Silently Handled
Fixed a JavaScript SecurityError thrown when the Opensolr search page is embedded inside a cross-origin iframe. Browsers block showPicker() calls from cross-origin frames; the call is now wrapped in a try/catch so the browser restriction is silently handled instead of surfacing as an uncaught exception that could disrupt other search functionality on the host page.
Fix Four Search Parameter Fixes: Wildcard Highlighting, hl.q, Stats and Currency Facets
Fixed four search parameter bugs across all platforms. (1) Wildcard searches (*:*) no longer send any highlighting parameters to Solr — highlighting on a catch-all query is meaningless and wastes server cycles. (2) The Solr highlight query (hl.q) was incorrectly set to *:* instead of the real search terms, so highlighted snippets never matched actual keywords. (3) A hardcoded stats=true / stats.field=price_f block was attached to every query even for non-commerce indexes. (4) currency_s was hardcoded into the facet field list regardless of whether the index has that field. All four are fixed in Opensolr, the Drupal module, and the WordPress plugin.
Improved Locale Facet Shows Flags and Language Names Across Opensolr Search, Drupal and WordPress
Locale facet — flags and readable names throughout the search UI. The Locale sidebar facet now shows flag emojis and language names instead of raw locale codes: hr_hr becomes 🇭🇷 Croatian, sr_sr becomes 🇷🇸 Serbian, and so on. The top-right All Locales selector panel also displays the correct country flag beside each language group. Active locale filters — whether applied from the sidebar facet or the top-right panel — appear as removable pills labelled with flag and name. Languages without a canonical country flag (e.g. Latin, constructed codes) show a 🌐 globe icon. Applied across the Opensolr search page, Drupal module, and WordPress plugin.

Admin Apr 22, 2026

Improved Web Crawler Control Buttons Aligned in a Uniform Two-Column Grid
WebCrawler — control buttons (Start/Stop Schedule, Reindex All, Reindex From Scratch, Stop Crawl, Pause/Resume, Flush to Solr) are now equal width and arranged in a clean two-column grid. Previously they were free-flowing flex items at varying widths; the container is now a two-column CSS grid so each button occupies a uniform cell.
Improved Index Settings: All Five Search Mode Options Now Fit on a Single Row
Index Settings — Search Mode radio buttons now sit on a single row. Previously the five options (Union, KW Required, Meaning Req., Intersection, Lexical Only) broke across two rows with the last one orphaned; the grid was widened from 4 to 5 columns so all five fit neatly side by side.

WordPress Apr 22, 2026

New Opensolr Search for WordPress 1.0.7 Adds the Lexical Only Search Mode
Opensolr Search for WordPress 1.0.7 — adds the Lexical Only search mode, matching the Opensolr admin and Drupal module. Explicit opt-out from vector: no embedding API call is made, search runs through the lexical edismax path. The Minimum Relevance Score slider auto-zeroes the moment the radio is picked (backend enforces this on save and at query time as well). Yellow note in Search Mode explains the coupling.

Drupal Apr 22, 2026

New Opensolr Search for Drupal 3.5.0 Adds the Lexical Only Search Mode
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.

Search Apr 22, 2026

New New Lexical Only Search Mode Skips Embeddings for Pure BM25 Ranking
New Lexical Only search mode in Search Tuning → Search Mode. Explicit opt-out from vector — no embedding API call is made, search runs straight through the lexical edismax path. Useful for deterministic BM25 ranking, avoiding embedding API latency, or users on plans without vector who want explicit control instead of the implicit server-side fallback. When selected, the Minimum Relevance Score slider auto-zeros itself (that threshold is calibrated for the combined hybrid score; a positive value would filter out every result in pure lexical mode) and a yellow note explains the coupling.

WordPress Apr 21, 2026

New Opensolr Search for WordPress 1.0.5 Adds the Minimum Relevance Score Slider
Opensolr Search for WordPress 1.0.5 — adds the Minimum Relevance Score slider to Search Tuning, matching the feature in the Opensolr admin and Drupal module. Drops low-scoring hybrid hits from results and facet counts, cleaning up catalog and content searches. Slider is in 0.1 increments, default 0.3.

Drupal Apr 21, 2026

New Opensolr Search for Drupal 3.4.0 Adds the Minimum Relevance Score Slider
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.

Search Apr 21, 2026

Fix Custom Minimum Match Values No Longer Truncated by the XSS Filter
Fixed custom Minimum Match values not saving. Values containing the less-than character (e.g. 2<95% 5<90% 8<80%) were silently truncated to just the first number because the global XSS filter stripped the < before the value reached the save handler. The tuning form now reads the raw request body for this field — custom mm presets save and apply correctly.
Improved Search Page Pagination Moved Into the Results Column, Top Block Removed
Search page pagination layout cleaned up — pagination is now rendered inside the results column instead of drifting to the left under the facet sidebar, and the redundant top pagination block (which appeared next to the "Did you mean" spellcheck line) has been removed. Pagination now lives only at the bottom of the results, aligned with the rest of the content.
New Search Operators Help Panel: Phrase Match, Required, and Excluded Terms
New Search Operators help button next to the Search bar. Opens a panel explaining "phrase match", +required, and -excluded operators with examples and a note on why they matter in hybrid search. Users can now refine queries like +laptop "13 inch" -refurbished and cut through semantic noise instantly.
New New Minimum Relevance Score Slider Filters Low-Scoring Hybrid Search Hits
New Minimum Relevance Score slider in Search Tuning. Drops hits whose combined lexical + vector score falls below the threshold, cleaning noise out of facet counts and result totals. Essential for hybrid search on catalog-style content — without it, numFound balloons to the entire filter set and facet counts pick up docs the user would never consider relevant. Slider moves in 0.1 increments, default 0.3, 0 disables.

Analytics Apr 21, 2026

New Query Analytics: Export Every Dashboard Table to CSV
Export CSV from Query Analytics — every table in the Analytics Dashboard (Popular Queries, Latest Queries, Path Distribution, Queries Over Time, Per-Server Stats) now has a green Export CSV button. Downloads are UTF-8 BOM-encoded for Excel compatibility, and the Latest Queries export respects your active filters (search, HTTP status, IP address).
Improved Faster Query Analytics: 30-Minute Caching and 30-Day Default Query Window
Faster Query Analytics — Popular Queries, Latest Queries, Path Distribution and Per-Server metrics now load noticeably faster across the dashboard. Historical analytics results are cached for 30 minutes (up from 5), single-hit noise is filtered out of "popular" results, and the default window for Popular/Latest Queries was expanded from 10 to 30 days so you get more context out of the box.

WordPress Apr 10, 2026

Fix WordPress Plugin: Sitemap Registration Fix, Setup Progress Modal, WooCommerce Meta Tags
Fixed WordPress plugin Save & Connect not registering the sitemap URL with the crawler, and Save & Start Fresh not deleting the previous index. Also added full-screen progress modal with step-by-step status and error reporting during setup, and improved product meta tag injection for WooCommerce (BreadcrumbList, price, currency, product categories).

Drupal Apr 10, 2026

Fix Opensolr Search for Drupal 3.3.3: Sitemap Registration on Save and Connect Fixed
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.

Search Apr 10, 2026

Improved Hybrid Search Relevance: Lexical Field Boosts Zeroed in Vector Mode
Improved hybrid search relevance — in vector hybrid mode, lexical field weight boosts are now automatically zeroed out so that semantic similarity drives the relevance ranking. Previously, even small lexical boosts could inflate scores well above the 0-1 vector range, pushing semantically relevant results down. Field weights still apply when search falls back to pure lexical mode.

New WordPress Partner Program: 50% Off Small and Medium Plans for a Full Year
WordPress Partner Program — WordPress plugin users now qualify for 50% off any small or medium plan for a full year. Same deal as Drupal — install, use, provide feedback. Apply from the pricing page.

Data Ingestion Apr 9, 2026

Fix Data Ingestion API Fix: PHP 8 Issue Caused Empty Responses on All Endpoints
Fixed Data Ingestion API endpoints returning empty responses. A PHP 8 compatibility issue in the API layer caused all ingestion, embedding, and AI endpoints to silently fail. Restored full functionality for ingest, embed, ai_summary, and all related API calls.

Search Apr 9, 2026

Fix Query Elevation Controls Restored on the Hosted Search Page With Instant Effect
Fixed Query Elevation controls not appearing on the hosted search page. Token-based authentication now accounts for CAPTCHA verification time, and elevation settings take effect immediately after toggling (previously required up to 10 minutes due to caching).

Data Ingestion Apr 9, 2026

Improved Data Ingestion Queue Dashboard Redesigned to Handle Thousands of Jobs
Data Ingestion queue dashboard redesigned for scale — indexes and jobs now load progressively on click instead of all at once. Per-index progress dialog shows real-time status for each index separately. Handles thousands of jobs without performance degradation.

Drupal Apr 9, 2026

Fix Drupal Query Elevation: Remove Button No Longer Shows Without Elevation Rules
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.

Search Apr 9, 2026

Improved Search Page Shows Results Count Under the Search Bar and Response Time in Seconds
Search results count now appears directly below the search bar for immediate feedback. Response time displayed in seconds (e.g. 0.09 s) instead of milliseconds. Price and date facet sliders stay visible even when filters narrow results to a single item.

Data Ingestion Apr 9, 2026

Improved Data Ingestion Enrichment: Structured Text Embeddings and Smarter Sentiment Analysis
Improved Data Ingestion enrichment pipeline — embeddings now use structured text (text_t) when available for richer semantic vectors. Sentiment analysis uses first 10 complete sentences instead of just title + description. Document size field now computed automatically.
Fix Duplicate Document Fix: URI Normalization Unifies Web Crawler and Data Ingestion IDs
Fixed duplicate documents when using both Web Crawler and Data Ingestion on the same index. URIs are now normalized (trailing slash stripped) before computing the document ID, so both methods produce the same document instead of duplicates.

Improved Price Filter Topbar Slider Tooltips Get Consistent Thousands Separators
Price filter topbar slider tooltips now show thousands separators (e.g. 15,638.00 instead of 15638.00). Consistent number formatting across all slider controls, tooltips, and input fields.

Drupal Apr 4, 2026

Fix Drupal Module Safari and iOS Fixes: Show-More Buttons, Slider Loading, and Z-Index
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 Drupal Facets: Per-Facet Minimum Count Threshold and Instant CSS Tooltips
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 Drupal Hierarchical Drill-Down Facets Auto-Detected From JSON-LD Breadcrumbs
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.

Web Crawler Apr 4, 2026

Improved Web Crawler Date Extraction From Date-Related CSS Classes on Sites Without Metadata
Improved web crawler date extraction for sites that lack JSON-LD or meta tags. New targeted extraction looks for dates inside HTML elements with date-related CSS classes (e.g. .date, .posted, .info) — much safer than scanning all page text.
Fix Web Crawler Date Indexing Fix: Timezone Offsets Now Strictly Converted to UTC
Fixed date indexing errors caused by timezone offsets (e.g. +03:00) in date fields. All dates are now strictly converted to UTC before sending to Solr. Added a final safety gate — any date that doesn't match the exact Solr format is dropped rather than causing an indexing error.

Search Apr 4, 2026

Improved Active Filter Pills Show Thousands Separators in Price and Facet Values
Active filter pills now show numbers with thousands separators (e.g. "Price from: 9,507.99" instead of "9507.99"). Applies to both the facet sidebar pills and the topbar price filter pills.
Improved Facet Slider Inputs Display Thousands Separators and Smart Decimal Formatting
Facet slider inputs now display numbers with thousands separators (e.g. 15,637.00 instead of 15637.00) for better readability. Float fields (_f) show 2 decimals, integer fields show none. Min values are floored and max values are ceiled so the range always covers all results.

Improved Homepage Drupal Card Showcases Opensolr Search Module and Vector Search E-Commerce Demo
Homepage Drupal card updated — now showcases the Opensolr Search for Drupal module with full-text search, facets, analytics, and AI features. New vector search e-commerce demo added to the live demos section.

Web Crawler Apr 3, 2026

Improved Web Crawler Skips Embedding Generation on Indexes Without AI Vector Access
Web Crawler now respects the package's vector access flag — indexes without AI features skip embedding generation during crawls, saving GPU resources and speeding up indexing.

Control Panel Apr 3, 2026

New Search Facet Filters Admin Panel: Map Solr Schema Fields to List, Slider, and Date Widgets
Search Facet Filters configuration section in the admin panel — discover all indexed fields via Solr schema, map them as list, slider, or date range widgets, drag to reorder. Embeddable search also supports facets via data-sidebar="on".

Performance & SEO Apr 3, 2026

Improved GPU Priority Queue Puts Search Embeddings Ahead of Crawler Batch Jobs
GPU priority queue for AI embeddings — user-facing search requests now always jump ahead of background crawler batch jobs. Prevents slow search during heavy indexing. Includes a configurable timeout so search falls back to lexical instantly if the GPU is busy.

API Apr 3, 2026

New AI and Vector Features Now Gated per Package With Friendly Upgrade Prompts
AI and vector features (AI Hints, AI Reader, Vector Embeddings, Hybrid Search) are now gated per package. Indexes without vector access get a friendly upgrade prompt instead of a generic error. Lexical keyword search continues to work on every plan.

Search Apr 3, 2026

Fix More Reliable Search Highlighter Fixes Keyword Highlighting in Short Title Fields
Fixed search result highlighting — switched to a more reliable highlighter that correctly highlights keywords in short fields like titles. Also added text_t (structured text) to highlighted fields for richer snippets.
Improved Search Header Stays Fixed at the Top While Scrolling Through Results
Search header now stays fixed at the top while scrolling through results, keeping the search box and controls always within reach.
Improved Search Transitions Now Show a Loading Overlay With Animated Dots
Search transitions now show a loading overlay with animated dots, so you know the search is working — especially helpful on slower connections or large indexes.
