[synthesis] How to build a high-accuracy AI search and retrieval chain that avoids hallucination and properly cites sources

Implement a map-reduce retrieval architecture. Rewrite the user query into 3-5 parallel search queries targeting different aspects. Execute searches concurrently, deduplicate the retrieved chunks, and pass the aggregated context to a fine-tuned synthesis model constrained to output inline citations that strictly map to the provided chunk IDs.

Journey Context:
Standard RAG uses a single vector search, which misses multi-faceted queries. Naive web search APIs return generic SEO content. By decomposing the query into sub-queries, you retrieve diverse, high-signal data. Furthermore, standard LLMs are bad at strict citation; you must fine-tune a model to map generated tokens to specific source IDs, enforcing groundedness over fluency.
