Hello @sergej-d,
I'm Dosu, a bot here to assist while we wait for a human maintainer. I'm here to help you troubleshoot issues, answer questions, and guide you in contributing to the project. Let's work together to find a solution!
Based on the information you've provided and the similar issues I found in the LangChain repository, it seems like you want to prevent the ConversationalRetrievalChain from returning sources for questions without sources.
To achieve this, you can set the return_source_documents attribute to False when initializing the ConversationalRetrievalChain class. This attribute controls whether the retrieved source documents are returned as part of the final result. Here is an example of how to do this:
chain = ConversationalRetrievalChain(
combine_docs_chain=combine_docs_chain,
retriever=retriever,
question_generator=question_generator_chain,
return_source_documents=False, # Set this to False
)This is supported by the following code in the BaseConversationalRetrievalChain class:
return_source_documents: bool = False
"""Return the retrieved source documents as part of the final result."""And in the _call and _acall methods, the source documents are only added to the output if return_source_documents is True:
if self.return_source_documents:
output["source_documents"] = docsYou can find this in the BaseConversationalRetrievalChain class definition.
Please note that the default value of the return_source_documents attribute in the ConversationalRetrievalChain class is False. If you're still seeing sources returned, it might be due to some other part of your code overriding this default.
I hope this helps! If you have any other questions or need further clarification, feel free to ask.
Best, Dosu

Issue you'd like to raise.
Hi,
I am wondering if anyone has a work around using ConversationalRetrievalChain to retrieve documents with their sources, and prevent the chain from returning sources for questions without sources.
query = "How are you doing?" result = chain({"question": query, "chat_history": chat_history}) result['answer']
""" I'm doing well, thank you.
SOURCES: /content/xxx.pdf """
