https://opensolr.com/ Opensolr changelog, guides and documentation: managed Solr hosting, AI hybrid search, web crawler and RAG API updates. en Thu, 03 Sep 2026 18:41:45 +0000 https://opensolr.com/changelog/entry/search-by-image-barcode-qr-code-scanning https://opensolr.com/changelog/entry/search-by-image-barcode-qr-code-scanning Search by image now also reads barcodes and QR codes: point it at a product barcode, a poster's QR code, or a shipping label, and it is decoded automatically, no separate scanner needed. Combined with the labels it already recognizes and the text it already reads off a picture, search by image now works in three layers: what the picture shows, what is printed on it, and any code on it. See it on the demo page. Search Thu, 03 Sep 2026 00:00:00 +0000 https://opensolr.com/changelog/entry/search-by-image-reads-labels-ocr-shelf-tag-exact-product https://opensolr.com/changelog/entry/search-by-image-reads-labels-ocr-shelf-tag-exact-product Search by image now reads a picture when it is mostly text: a shelf tag, a spec label, a receipt. The product name and the article number on it become the query, and the exact product comes back first. Pictures of things still work as before. Nothing to set up, nothing to re-index; the same is in the image_to_text API. Search Thu, 03 Sep 2026 00:00:00 +0000 https://opensolr.com/changelog/entry/search-by-image-upload-a-photo-image-to-text https://opensolr.com/changelog/entry/search-by-image-upload-a-photo-image-to-text Every Opensolr hosted search page now takes a photo as the query: click the image icon next to the search box, pick a picture, and the search runs on what is in it. The same thing is available to your own code as the image_to_text API endpoint. Search Tue, 01 Sep 2026 00:00:00 +0000 https://opensolr.com/changelog/entry/query-analytics-utf8-fix-popular-queries-real-searches https://opensolr.com/changelog/entry/query-analytics-utf8-fix-popular-queries-real-searches Two fixes to Query Analytics. Searches containing accented and international characters are now reported UTF-8 correctly instead of showing up garbled, and the Popular Queries chart now shows the searches your visitors actually typed — facet and filter clicks are no longer counted as queries, and real searches are no longer hidden by a popularity threshold. Query Analytics Tue, 01 Sep 2026 00:00:00 +0000 https://opensolr.com/changelog/entry/control-panel-dropdowns-size-to-content https://opensolr.com/changelog/entry/control-panel-dropdowns-size-to-content Every dropdown in the Control Panel now sizes to its own content instead of taking half a screen. Filter bars on the log and analytics screens fit on one line again.

Four settings that could never be saved now save.

The same release reworks interface details across the site, most visibly the pricing and ordering flow.

The PIN, EXCLUDE and EXCLUDE ALL buttons on the search results page now save rules instead of returning a permission error, EXCLUDE ALL rules are now read by the search itself, and deleted or replaced documents no longer stay searchable.

All are now read correctly by both the Data Ingestion API and the Web Crawler. Data Ingestion Mon, 31 Aug 2026 00:00:00 +0000 https://opensolr.com/changelog/entry/integration-packages-0-3-0-live-test-suite-fixes https://opensolr.com/changelog/entry/integration-packages-0-3-0-live-test-suite-fixes The LangChain, LlamaIndex, Haystack, MCP and Laravel Scout packages are out at 0.3.0, covered end to end by a live test suite that found three bugs, and each one now ships with public demo credentials so the quickstart runs with nothing to sign up for.

AI Hints now reads the full text of the most relevant matches from your index instead of the teaser lines on screen. Drupal Sat, 29 Aug 2026 00:00:00 +0000 https://opensolr.com/changelog/entry/fresh-toggle-visitors-push-recent-results-up-ranking https://opensolr.com/changelog/entry/fresh-toggle-visitors-push-recent-results-up-ranking A Fresh toggle lets whoever is searching push recent documents up the ranking, with a per-index weight slider deciding how hard it pushes. AI Hints answers are far more detailed, read the full text of every relevant match, and are now identical across the search page, the modules and all five packages.

Enabling a dedicated PHP-FPM pool gives that project its own PHP error log automatically, and the viewer reads the path straight from the pool configuration. Server Management Sat, 29 Aug 2026 00:00:00 +0000 https://opensolr.com/changelog/entry/server-management-dedicated-php-fpm-pool-per-project https://opensolr.com/changelog/entry/server-management-dedicated-php-fpm-pool-per-project Each project on a managed server can now run on its own PHP-FPM pool, so one busy site cannot exhaust the workers of every other site on the box. Live worker counters and a pool file editor are included, and the change is strictly opt-in.

The API Reference was rewritten around real error responses and the two hosts, api.opensolr.com now serves only AI and Data Ingestion, and three endpoint bugs were fixed.
