REST APIs for everything

70+ documented endpoints · Full API reference

Building RAG or AI agents? Six ways in.

Pick your ecosystem. Underneath it is 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. Listed in the official MCP Registry as com.opensolr.

Product page MCP Registry GitHub

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.

Product page PyPI GitHub

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.

Product page Packagist GitHub

REST API

any language

Not on Python or PHP? The same GPU endpoints are plain HTTPS: 1024-dimension multilingual embeddings, hybrid semantic search, and streaming RAG answers generated from your own indexed content.

Search that gets what people actually mean.

Sometimes people search for what something does, not what it is called. Search for “see heat through walls” on a tools site and 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.
