In Hybrid Search, searchers such as BM25 and Vector Search run independently, produce separate result sets, and get merged...

Introducing ... ... Wormhole Vectors!

Instead of merging orthogonal results, traverse between the vector spaces. Run a lexical search, pool the matching documents' dense vectors, and search the dense space from that point.

Hybrid search runs two queries and hopes the right answer was in one of them. Wormhole vectors let you traverse between the spaces instead.
