Cross Application Unified Search

via “multi-index federated search with result merging”

Lightning-fast search engine with vector search.

Unique: Implements federated search by executing queries in parallel across multiple indexes and merging results using configurable weighting, enabling cross-collection search without requiring index consolidation. Results are ranked by combined relevance scores from all indexes.

vs others: Simpler than Elasticsearch cross-cluster search because it operates on local indexes without network overhead; more flexible than Solr collection aliasing because it supports per-index weighting and dynamic index selection.
