AWS explains how agentic retrieval fixes partial answers in LangChain and Bedrock RAG apps

Why it matters

If your support assistant answers comparison questions, one blended search returns relevant-looking chunks that cover only part of the question.

Ask your team

Do our assistant's answers to multi-part questions cover every part, or only the part the search matched?

What happened

AWS shows how to pair LangChain with Knowledge Bases so a assistant splits a multi-part question into separate searches. A single query vector blurs all the intents together, so answers cover only part of what was asked.
