Managed Apache Solr cloud — search, hybrid AI & RAG for any site or app.
Managed Apache Solr since 2011 · 15 years in production
Lexical, vector & hybrid search on fully managed Solr — with GPU embeddings, web crawling, and RAG APIs built in.
One-click modules for Drupal & WordPress, a LangChain vector store for Python, REST for everything else.

Building RAG or AI agents? Six ways in.
Pick your ecosystem — underneath it's the same managed Solr cloud, the same server-side GPU embeddings, the same hybrid BM25 + kNN engine.
LangChain pip install langchain-opensolr
Native vector store in the official LangChain directory. The shortest setup in the list — an API key and an index name — then every chain, agent, and RAG tutorial ever written just works.
MCP · AI Agents uvx opensolr-mcp
Claude, Cursor, or any MCP agent gets your search as native tools: hybrid retrieval, indexing, grounded RAG answers. The chat is the UI. In the official MCP Registry as com.opensolr.
LlamaIndex pip install llama-index-opensolr
OpensolrVectorStore + OpensolrEmbedding under the standard namespace. HYBRID query mode with tunable alpha, standard metadata filters — your index, retriever, and query engine work unchanged.
Haystack pip install opensolr-haystack
DocumentStore + hybrid retriever for Haystack pipelines, with zero embedder components — documents and queries embed server-side on our GPUs. Full protocol, saved-pipeline serialization.
Laravel Scout composer require opensolr/laravel-scout-opensolr
Model::search() with hybrid semantic relevance — "sleepy pets" finds the post about cats napping. One index serves all your models, so a single plan covers the whole application.
REST API any language
Not on Python or PHP? The same GPU endpoints are plain HTTPS: 1024-dim multilingual embeddings, hybrid semantic search, and streaming RAG answers generated from your own indexed content.
One click to plug it into your site
Whether you run Drupal, WordPress, or built your site yourself — we've already done the integration work. Pick your stack.
Got a Drupal site?
Two free modules on drupal.org. Pick the one that suits how you work — both are official, both are maintained by us.
Drupal Opensolr Search is the one we recommend: a standalone module with no Search API dependency. Install it, click „Connect”, and your site has search — multilingual content, WooCommerce/Commerce, and custom content types included. See the product page →, the documentation, the Drupal.org project, or the complete guide.
Search API Opensolr is the drop-in: already using Search API Solr? Switch to us in one config change — it auto-configures everything and keeps your existing setup and index config. Grab it on Drupal.org →, then follow the setup guide or the connection FAQ.
Got 50 Drupal sites? No problem. Each site gets its own search index, one click each — we never limit you to one site or one index.
Set Up DrupalGot a WordPress site?
A free plugin in the official WordPress directory. WooCommerce ready, multilingual ready, and a real one-click install — no setup wizard, no configuration hell.
Opensolr Search for WordPress indexes everything that matters: WooCommerce products, posts, pages, custom types, even attached PDFs — all searchable, with hybrid search out of the box. Works with WPML and Polylang. Start on the product page →, read the documentation, install from WordPress.org →, or check the FAQ & setup.
Multisite WordPress? Each site gets its own search index, one click each. Run one site or a hundred — same simple flow.
Set Up WordPressBuilt your site yourself?
Whatever you build with — Symfony, Laravel, Rails, Django, Node.js, .NET, a custom CMS, or a static site generator — we have a simple REST API for it. Push documents in JSON, get results in JSON, authenticate with an API key. Start with the full API reference →, the push docs API, or a real Laravel example.
No time for a search UI? Point your visitors at search.opensolr.com/your_index — already styled, already responsive, done. Here is how to embed it and the search page guide.
No time for integration at all? Give us your sitemap URL and our Web Crawler indexes your whole site for you — see getting started.
Multiple indexes? Multiple sites? Knock yourself out. One account, unlimited indexes, unlimited sites — each independent, each one click.

Smart search that gets what people actually mean
Sometimes people search for what something does, not what it's called.
Our smart search figures that out. Search for "see heat through walls" on a tools site → it finds "thermal cameras". No keyword match. Pure understanding.
Smart Search
Finds the meaning behind a search, not just the words. Mixes classic keyword matching with deep understanding for the best of both worlds.
