RediSearch/RediSearch

RediSearch is a powerful Redis module that transforms Redis into a robust search and query engine, offering secondary indexing, full-text search, and vector similarity capabilities.

Core Features

Full-text indexing across multiple fields with incremental updates.

Vector similarity search (KNN, filtered KNN) for AI applications.

Advanced query features including boolean logic, prefix, fuzzy, and phonetic matching.

Powerful aggregations engine for complex data analysis.

Document ranking with BM25 and user-provided weights.

Detailed Introduction

RediSearch extends Redis by providing a sophisticated query and indexing engine, enabling developers to perform advanced search operations directly on their Redis data. It leverages compressed, inverted indexes for efficient storage and fast retrieval, supporting features like exact-phrase matching, fuzzy search, and numeric filtering. Integrated into Redis 8+, RediSearch eliminates the need for separate search infrastructure for many use cases, making Redis a more versatile data platform for real-time search, AI-powered applications, and complex data aggregations.
