RAG That Works: Retrieval, Not Magic

🎓 3 levels📚 12 lessons

1. Why Retrieval Fails

  • RAG is search before it is generation
  • Chunking: the decision with the most impact and the least thought
  • Embeddings: what they capture and what they do not
  • Measuring retrieval on its own

2. Retrieving Better

  • Hybrid search: why BM25 is still alive
  • Reranking: the step almost nobody adds
  • Metadata and filtering: the cheapest improvement
  • The user's question is not the search query

3. RAG in Production

  • Lost in the middle: context order matters
  • Citing, and knowing how to say you do not know
  • The index changes: maintenance and data that expires
  • When RAG is not the answer
