Type of issue

issue / bug

Language

Python

Description

In this reference document: https://reference.langchain.com/python/langchain-classic/chains/retrieval/create_retrieval_chain

I found out that the import for create_retrieval_chain() is:
from langchain_classic.chains import create_retrieval_chain

However it is incorrect, based on the official LangChain github repository, it should be:
from langchain_classic.chains.retrieval import create_retrieval_chain
