Opensolr Changelog — Recent Updates & Improvements

Search Jul 24, 2026

New Hybrid search now runs on the Opensolr {!hybrid} parser. Every vector-enabled index now fuses keyword (BM25) and semantic (vector) relevance through {!hybrid} — a proprietary Opensolr Solr query parser that runs only on Opensolr clusters. You get correct score fusion, real search-mode semantics (Union / Keywords Required / Meaning Required / Intersection), and natural-language, cross-lingual queries that just work — plus semantic search over documents.

New Live Varnish & Memcached stats in Server Management. Every running Varnish or Memcached service in your server’s Services tab now has a Stats button — one click opens a clear snapshot of how your cache is really performing: overall hit rate, requests served straight from cache versus fetched from the backend, objects stored, memory used, evictions and more. Hover any metric’s info icon for a plain-English explanation, and see exactly how long the counters have been running. Read more in the Server Management docs.

New New Security & Trust Center. Read how Opensolr protects your data — our security controls mapped to the SOC 2 Trust Services Criteria and ISO 27001, with a downloadable overview for your vendor security reviews. Visit the Trust Center.
