Module 6: Best Practices (Optional)

This module was recorded in 2024 and has not been updated since then. It covers techniques that improve RAG retrieval quality: hybrid search, document reranking, and how to implement them with Elasticsearch and LangChain.

It is optional - the techniques are still relevant, but the code uses older libraries and approaches.
