Code lab 10.2 – LangChain Retrievers

In this code lab, we will cover a few examples of the most important component in the retrieval process: the LangChain retriever. Like the LangChain vector store, there are too many options for LangChain retrievers to list here. We will focus on a few popular choices that are particularly applicable to RAG applications, and we encourage you to look at all the others to see if there are better options for your specific situation. Just like we discussed with the vector stores, there is ample documentation on the LangChain website that will help you find your best solution: https://python.langchain.com/v0.2/docs/integrations/retrievers/

The documentation for the retriever package can be found here: https://api.python.langchain.com/en/latest/core_api_reference.html#module-langchain_core.retrievers

Now, let’s get started with coding for retrievers!
