LangChain Multi-Query Retriever for RAG

In this video, we'll learn about an advanced technique for RAG in LangChain called "Multi-Query". Multi-query allows us to broaden our search score by using an LLM to turn one query into multiple, allowing us to search a broader vector space and return a higher variety of results. In this example, we use OpenAI's text-embedding-ada-002, gpt-3.5-turbo, Pinecone vector database, and of course the LangChain library.
