What you'll learn
Structure documents so retrieval actually works
Choose chunking and metadata that hold meaning together instead of splitting it apart.
Build the retrieval and ranking layer
Move past basic similarity search to hybrid retrieval and reranking that surfaces the right passage.
Measure retrieval quality with real numbers
Score retrieval directly, so you know the system is working before users tell you it is not
Diagnose the three ways RAG fails in production
Recognise chunking, retrieval and staleness failures from the symptoms users report.
Why this topic matters
Most teams have RAG running and quietly know it is not good enough. Answers are vague, citations are wrong, and nobody can say why. The instinct is to swap the model or rewrite the prompt, which rarely helps, because the failure is almost always in chunking, retrieval or the absence of any real measurement. Three engineers build the whole pipeline properly, in one session.
