Typesense is a search engine designed to deliver responsive, relevant results for websites and applications. It provides an alternative to hosted search services, offering a self-hosted search server with an HTTP API and a range of tools for developing search experiences.
The engine is particularly suited to applications that need results to appear while users are typing. It handles common spelling mistakes and provides configurable ranking rules, allowing developers to balance textual relevance with business-specific ordering criteria.
Typesense supports structured filtering and faceted navigation, making it useful for catalogues, directories and other collections where users need to narrow results by attributes. Applications can also perform searches based on geographic coordinates.
Alongside conventional keyword retrieval, Typesense provides vector similarity and hybrid search. These capabilities allow developers to build search experiences that combine exact text matching with semantic retrieval.
The engine includes clustering and replication facilities for running a search service across multiple nodes.
This is free and open source software.
