Report #79522

[frontier] Vector similarity search returns irrelevant chunks for complex multi-part queries—how do I make retrieval dynamic?

Implement Agentic RAG: use a planner agent to decompose queries, route to specific retrievers \(SQL, vector, API\), and synthesize results.

Journey Context:
Standard RAG \(chunk -> embed -> similarity search\) fails on complex queries requiring multiple hops or structured filters \(e.g., 'products under $50 released in 2024'\). The fix is treating retrieval as an agentic workflow: a 'retrieval planner' analyzes the query, decides which sources to query \(vector DB, SQL database, web search\), executes in parallel, and grades results before synthesis. This replaces static retrieval pipelines with dynamic tool use. Key insight: the retriever itself becomes an agent with access to tools, not just a vector search. This pattern is replacing naive RAG in production systems by Q2 2025. Tradeoff: higher latency and cost per query, but dramatically better accuracy on complex questions.
