Improved 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.

Fix 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 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 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.

Improved 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 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.

Improved 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 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 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.

Improved 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.

New 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".

Improved 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.

New 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.

Fix 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 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, so you know the search is working — especially helpful on slower connections or large indexes.
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.
