Opensolr Changelog — Recent Updates & Improvements

Search Apr 22, 2026

New 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.

New 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 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.

New Facet filter sidebar — filter search results by category, price, date, and any structured field. Supports list facets, numeric sliders, and date range pickers. "Show more" dialog with letter index for browsing large facet lists. Active filters shown as removable pills. Configure facets from the admin panel under Search Facet Filters.
