Opensolr Changelog — Recent Updates & Improvements

Drupal Module Aug 18, 2026

Improved Search API opensolr 2.4.0 — new guided setup page. The Search API opensolr module's "Get started" tab is now a four-step guide that ticks off what you have already done: create your Opensolr account (15-day free trial), paste your email and API key, let Autoconfigure create the index and Search API server, then add your Search API index as usual. The old in-Drupal registration wizard, which relied on a retired API, is gone.
Improved Search API opensolr 2.3.0 — we now maintain the Search API connector. The Search API opensolr module (the drop-in Search API Solr connector for Opensolr) is now maintained by the Opensolr team. 2.3.0 fixes the admin fatal error that could appear when the Opensolr API was unreachable or an API key had been changed, makes the Key module integration an explicit opt-in (installing Key for something else no longer breaks your credentials), and is ready for Drupal 12. Drop-in update: run database updates after upgrading.

Improved AI answers now answer your question — not just summarize. When you ask a question on your hosted search page, the AI insight now formulates a direct, structured answer grounded strictly in your indexed content, with bold section headers — instead of a generic summary. The same grounded answer mode powers ai_answer in all AI integrations, with configurable retrieval depth (how many documents and how much text feed the answer) and an optional custom instruction (answer language, citation style, extraction tasks).

Improved embed_and_search now matches your hosted search page exactly. The one-shot hybrid search endpoint runs the platform’s full tuned pipeline: your index’s saved Search Tuning applies automatically, natural-language questions are processed the same way as on your search page (stopwords cleaned for keyword matching, while the full phrase goes to the semantic embedder), and every tuning knob (fw_*, mm, search_mode, vector_topk, quality_boost, and more) accepts per-request overrides. Results returned via the API are now identical to your search page. Full parameter reference in the AI-Hints API guide.
Improved Your Search Tuning now applies everywhere — including all AI integrations. Everything you configure in Index Settings → Search Tuning (semantic↔lexical balance, field weights, minimum match, search mode, vector candidate pool, content quality boost) now applies automatically to every search and every RAG answer made through the LangChain, LlamaIndex, Haystack, Laravel Scout, and MCP integrations — the same tuned pipeline as your hosted search page. Each knob can also be overridden per call from code via the new tuning parameter. Packages updated: LangChain, LlamaIndex, Haystack (v0.2.5), Laravel Scout (v0.2.5), MCP (v0.2.6).

Improved All AI integrations upgraded to v0.2.0. Writes in every integration — LangChain, MCP, LlamaIndex, Haystack, Laravel Scout — now go through the Data Ingestion API: documents are queued and enriched server-side (embeddings, sentiment, language, and all derived fields — identical to the Web Crawler), with progress visible in your Control Panel. Every integration also gains a lexical-only mode: pure keyword search with zero AI quota that works on any Opensolr index, including non-vector ones. Plus delete-by-query support and server-side PDF/DOCX text extraction via rtf:true.

Improved Verified against WordPress 7.1. Opensolr Search is tested and marked compatible with WordPress 7.1 (due 19 August 2026), including the iframed block editor and the new client-side media processing. No action needed on your side.
Improved The WordPress search page now lives inside your own theme. Opensolr Search 1.0.25 turns /opensolr-search/ into an ordinary WordPress page, so your site header, navigation and footer wrap the search results exactly like every other page — no more standalone, theme-less screen. Because it is a real page, you can rename it, change its URL, add it to your menus or drop the [opensolr_search] shortcode on any other page; the search form, facets, sorting and pagination all follow wherever you put it. The page title above the search box is gone and the spacing is tightened, so results start right under your header. Grab it from WordPress.org or the plugin updates screen.

Improved Service availability by country. For security and compliance reasons, Opensolr accounts can no longer be created from, and payment methods can no longer be added from, the following countries: Albania, Bangladesh, Belarus, Bulgaria, Cambodia, Hong Kong, Indonesia, Iran, Iraq, Israel, Japan, Kuwait, Liechtenstein, Moldova, Pakistan, Romania, Russia, Singapore, Switzerland, Syria, Turkey, Ukraine, and Vietnam. Existing accounts are not affected. If you are based in one of these countries and you need an Opensolr index, this is not a final no — please reach out to us directly through our contact page and we will review your case individually and set your account up by hand.
