Search Merge

v1.0.0new

Search Merge combines result tables from multiple retrievers into one ranked output table. Use it when a workflow should query several retrieval surfaces and hand one merged result set to an Agent or downstream DAT consumer.

Add retrievers on the Source sequence, tune Topk and Rrfk, then pulse Searchandfuse or Fuse. Agent tool exposure is optional and should stay off until sources are configured.
