[synthesis] Agent uses single-shot RAG for complex queries, retrieving irrelevant context

Decompose complex queries into sub-queries, execute them in parallel or sequentially, and synthesize the results. Use the initial retrieval to refine subsequent searches \(iterative retrieval\).

Journey Context:
Standard RAG embeds the query and does a single vector search. Perplexity's architecture uses query decomposition and iterative retrieval. It classifies the query, breaks it down, searches, and may search again based on initial findings. This 'retrieve-then-reason' loop is crucial for high-signal answers in complex domains.
