Opensolr Search

AI-Powered Search for Drupal — Zero Configuration

Opensolr Search gives your Drupal site hybrid AI search (keyword + vector/semantic), AI-generated answers, autocomplete, faceted navigation, analytics, real-time content sync, and multi-site shared indexes — all from a single module with zero dependencies beyond Drupal core. No Solr schema editing. No field mapping. No indexing load on your server.

Two Ways to Index

Web Crawler Opensolr visits your pages externally — like Google. Indexes HTML, PDFs, DOCX, XLSX automatically. Zero Drupal load.
Data Ingestion API Push content directly from Drupal. Works behind firewalls. Real-time sync on every save/delete. Bulk ingestion via cron for 500K+ sites.
Both Ingestion for instant updates, crawler as a safety net. Both produce identical Solr documents.

What You Get

  • Hybrid AI Search — keyword (BM25) + semantic vector search (1024-dim multilingual embeddings), fused per-document by the proprietary Opensolr {!hybrid} parser: normalized score blending, real search modes (Union / Keywords Required / Meaning Required / Intersection), cross-lingual matching. "CMS hosting" finds "Drupal cloud deployment"
  • Multi-Site Shared Index — point any number of Drupal sites at one index (new in 4.1.0): create it on the first site, then choose "Use an existing index" on the others. One search across your whole site family, document IDs never collide
  • AI Hints — streaming AI answers above results, powered by RAG on your own content
  • AI Reader — full-screen AI summaries per document
  • Autocomplete — query suggestions + live Solr results in one dropdown
  • Faceted Navigation — auto-discovered from your schema. Lists, date ranges with Today / Last Week / Last Month presets, numeric sliders with thousands separators. Drag-and-drop ordering. Per-facet mincount thresholds
  • 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 any start level, back navigation, and "Show more" for large lists
  • Result Thumbnails — map any image, file or media field as the result thumbnail, on both crawler and ingestion paths
  • Smart Number Formatting — slider inputs, filter pills, and tooltips display thousands separators (e.g. 15,637.00). Float fields show 2 decimals, integers show none. Min/max boundaries are floored/ceiled to always cover all results
  • Spellcheck — "Did you mean?" with automatic collation
  • Query Elevation — visual PIN/EXCLUDE buttons directly on search results
  • Analytics Dashboard — queries, clicks, CTR, no-results, top URLs. Privacy-first (hashed IPs)
  • Search Tuning — field weights, semantic–lexical balance, search modes, minimum match presets, vector candidate pool, content quality boost
  • Multilingual — automatic locale filtering per Drupal language. Each translation = separate Solr doc. Cross-lingual semantic matching out of the box
  • Document Search — PDF, DOCX, XLSX, PPTX, ODT text extraction and indexing
  • Commerce — products with price, currency, categories, JSON-LD structured data. Price sliders with thousands-separated display
  • SEO Meta Tags — automatic OG, Twitter Cards, JSON-LD, canonical — no Metatag module needed
  • Persistent Filters — admin-configured Solr fq rules applied to every search
  • Embeddable Mode — optionally use Opensolr's hosted search UI instead of Twig templates
  • Dark Theme — full dark mode across all elements including slider inputs and facet tooltips
  • Infinite Scroll — or classic numbered pagination. Your choice
  • Safari & iOS Compatible — tested on real devices. Proper touch handling, async asset loading, no layout glitches
