[counterintuitive] Semantic vector search is sufficient for RAG retrieval

Use hybrid search \(combining vector search with keyword/BM25 search\) for robust RAG.

Journey Context:
Pure vector search fails on exact matches \(names, IDs, acronyms\) because embeddings smooth over specifics. BM25 catches exact tokens. Hybrid search leverages both semantic understanding and exact matching.
