RediSearch – Redis Powered Search Engine

RediSearch is a source available Full-Text and Secondary Index engine over Redis, developed byRedis Labs .

Supported Platforms

RediSearch is developed and tested on Linux and Mac OS, on x86_64 CPUs.

i386 CPUs should work fine for small data-sets, but are not tested and not recommended. Atom CPUs are not supported currently.

Redisearch implements a search engine on top of Redis, but unlike other Redis search libraries, it does not use internal data structures like sorted sets.

This also enables more advanced features, like exact phrase matching and numeric filtering for text queries, that are not possible or efficient with traditional Redis search approaches.

Official and community client libraries in Python, Java, JavaScript, Ruby, Go, C#, and PHP.

See theClients page for the full list.

Cluster Support and Commercial Version

RediSearch has a distributed cluster version that can scale to billions of documents and hundreds of servers. However, it is only available as part of Redis Labs Enterprise. We also offer official commercial support for RediSearch. See theRedis Labs Website for more info and contact information.
