RediSearch is a high-performance search engine built as a Redis module, enabling fast execution of complex search queries on large datasets. It was benchmarked against Elasticsearch and found to be 58% faster in indexing and 4 times faster in throughput, with slightly better latency. RediSearch's optimized data structures and native Redis protocol make it a viable alternative to other search engines. The engine's performance advantages are attributed to its C-based architecture, native memory technology, and dedicated search engine design.
