What are RediSearch and ZincSearch?
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
ZincSearch
ZincSearch is a lightweight, single-binary search engine that aims to be a simple, low-resource alternative to Elasticsearch. It provides a web UI and an Elasticsearch-compatible ingestion API.
- Single binary deployment
- Built-in web UI
- Elasticsearch-compatible bulk API
- Low resource requirements
