Distributed real-time search and secondary indexing engine optimized for performance

RediSearch is a fast search engine that enables you to query your recently indexed Redis data to answer any kind of complex question. Use it as a secondary index for datasets hosted on other data stores, a fast text search or auto-complete engine, and as a search engine that powers other modules like RedisGraph and RedisTimeSeries.

Rich with features, RediSearch supports many capabilities including ranking, boolean queries, geo-filters, synonyms, numeric filters and ranges, aggregation, and more, and even allows you to add your own custom scoring code.

Main capabilities

Scalable distributed search

Scale out and partition RediSearch over several shards and nodes for greater speed and memory capacity. Each shard holds only the part of the search index associated with all the documents residing on the shard. A search coordinator is responsible for coordinating the query execution across multiple shards of the cluster.

Support complex aggregation operations

Compose a pipeline of simple operations to develop advanced, aggregate queries to narrow down your search results. This incredibly powerful feature allows for data to not only be queried but summarized mathematically to deliver analytical insights.

Powerful autocomplete engine

Enrich your search experience with context-aware suggestions. Enable ‘fuzzy’ searching where exact matching is needed, and maintain suggestions dynamically based on queries and questions.
