Incremental Document Indexing Via Keyspace Notifications

A query and indexing engine for Redis, providing secondary indexing, full-text search, vector similarity search and aggregations.

Unique: Leverages Redis' native keyspace notification mechanism to detect document changes and trigger incremental index updates without explicit reindexing commands; integrates directly into Redis' event loop, avoiding separate indexing services or batch jobs

vs others: Simpler than Elasticsearch's refresh interval model because updates are event-driven rather than time-based; more efficient than application-level index management because indexing happens within Redis without round-trips
