Adding a Search Engine to Redis: Adventures in Module-Land

The Redis Modules API has enabled the creation of a super-fast and feature-rich search engine, RediSearch, from scratch using custom data types and algorithms. By utilizing Redis as a framework, RediSearch offers performance that client libraries cannot match. The search engine features include inverted indexing, auto-complete commands, fuzzy suggestions, and support for filtering and ranking results. Benchmarks have shown RediSearch outperforming other open-source search engines by significant margins, making it an attractive option for developers looking to enhance their Redis applications with advanced search capabilities.
