Overall, I think it was a great lecture. In particular, I have already developed a RAG service that retrieves answers using BM25+Vector, and I feel I can improve it further based on this course. However, one thing I wish there was more of is content on embedding techniques. I am currently chunking text or Markdown documents and storing them in a Qdrant vector database; I was hoping for some tips and know-how on how to efficiently store chunks and vector data, as well as how to retrieve that data effectively. Still, it was great to learn advanced technologies like GraphRAG and Agentic RAG!
