Summary
A RAG pipeline can retrieve perfectly and still give wrong answers. This video covers three ways that happens in production: outdated documents, vague or low-intent queries, and truth that depends on context, where several sources are each correct in different situations. For each one it gives a fix: document lifecycle management, a clarification loop before retrieval, and metadata that tells the system which source applies.
Key points
- Failure 1, outdated documents: perfect retrieval is useless if it returns an old or superseded policy.
- Fix for stale data: use document versioning, expiration dates and approval states, and remove superseded documents from the index.
- Failure 2, bad queries: a vague query like "applesauce?" should not go straight into retrieval.
- Fix for bad queries: add a clarification loop that checks whether the query has enough intent. If it doesn't, ask the user what they meant before retrieving.
- Failure 3, context-dependent truth: several documents can all be correct, such as federal policy, state policy and an internal company guideline.
- Fix for context-dependent truth: attach metadata (jurisdiction, source type, scope) and use the user's context so the system knows which source applies.
- Building a demo RAG app is easy. Making one work in production is a separate skill.

Try this
- Audit your RAG knowledge base for stale or superseded documents, and add versioning, expiration dates and approval states.
- Add a query-intent check or clarification loop before retrieval, so vague queries lead to a follow-up question.
- Tag documents with metadata such as jurisdiction, source authority and scope, so the system can pick the source that applies.
- Comment "RAG" on the post to get access to the creator's community and learning roadmap.
- Build a policy-QA RAG system with document lifecycle management (versioning, expiry, approval state) and automatic exclusion of superseded documents.
- Build a RAG app with a pre-retrieval clarification loop that detects low-intent queries and asks the user to clarify them.
- Build a multi-jurisdiction RAG assistant (federal, state and company policy) that uses metadata filtering to pick the applicable source.
