Semantic search (search by meaning) - Rails, OpenAI, langchain.rb, pg_vector

In this video, you'll learn how to use tools like OpenAI, LangChain.rb, and Postgres with pgVector to build semantic search for a Rails app, breaking content into chunks, generating embeddings for each chunk with OpenAI, storing those in Postgres, and then using nearest neighbor search to find relevant chunks for a search query. This allows searching by meaning rather than just matching text exactly.
