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, and real-time content sync — all from a single module
with zero dependencies beyond Drupal core. No Solr schema editing. No field mapping. No indexing load on your server.
→ Live Demo | Documentation | Product Page
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 + semantic vector search (BGE-m3, 1024-dim). "CMS hosting" finds "Drupal cloud deployment"
- 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, 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 - 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 — 10 parameters: field weights, semantic balance, freshness, mm, vector pool, quality threshold
- Multilingual — automatic locale filtering per Drupal language. Each translation = separate Solr doc
- 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
