# Acceptance

## Done

- `MilvusHybridKnowledgeStore`: schema BM25 function + dense, hybridSearch+RRFRanker, dense search
- `VectorSearchService` only routes dense|hybrid to V2 store
- `VectorIndexService` writes via V2 store
- Removed knowledge-path `MilvusServiceClient` bean wiring
- Config: `milvus.collection=biz_hybrid`, `retrieval.search.mode=hybrid`

## Tests

```text
mvn -Dtest=LookupKnowledgeToolTest,KnowledgeEvidencePostProcessorTest,RagResultProjectorTest,RrfFusionTest,VectorKnowledgeSearchAdapterHybridTest,VectorSearchServiceTest,VectorIndexServiceTest test
```

EXIT:0

## Ops note

Reindex all knowledge docs into `biz_hybrid` before production hybrid search is meaningful.
Legacy `biz` collection is unused by knowledge path.
