What are lnx and RediSearch?
lnx
lnx is an open-source search engine server built on top of the Tantivy library that exposes a simple REST API for indexing and querying documents. It aims to be a fast, easy-to-deploy alternative for full-text search.
- Built on Tantivy
- Simple REST API
- Fast full-text search
- Typo-tolerant queries
RediSearch
RediSearch, part of the Redis Query Engine, adds full-text search, secondary indexing and vector search capabilities to Redis. It enables fast querying over data already stored in Redis.
- Full-text search inside Redis
- Secondary indexing of Redis data
- Vector similarity search
- Aggregations and queries
