Embeddings and semantic search
What an embedding is, how cosine similarity finds texts that mean the same thing, how to create embeddings with Voyage AI, and where to store them.
Better retrieval: hybrid search, reranking and contextual chunks
Three techniques that fix most RAG retrieval failures: combining keyword and vector search, reranking the candidates, and adding context to every chunk.
RAG: retrieval-augmented generation
The full RAG pipeline: when you need it, splitting documents into chunks, retrieving the closest ones, and building a prompt that answers only from them.
