What are Pagefind and RediSearch?
Pagefind
Pagefind is a fully static search library that indexes a built website and serves search entirely from the browser without a backend. It is designed to be low-bandwidth and easy to add to any static site.
- Browser-side search index
- No backend required
- Low bandwidth
- Multilingual support
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
