Type Alias CreateRetrievalChainParams<RunOutput>

Type declaration

• combineDocsChain: RunnableInterface<Record<string, any>, RunOutput>

  Runnable that takes inputs and produces a string output. The inputs to this will be any original inputs to this chain, a new context key with the retrieved documents, and chat_history (if not present in the inputs) with a value of [] (to easily enable conversational retrieval).

• retriever: BaseRetrieverInterface | RunnableInterface<Record<string, any>, DocumentInterface[]>

  Retriever-like object that returns list of documents. Should either be a subclass of BaseRetriever or a Runnable that returns a list of documents. If a subclass of BaseRetriever, then it is expected that an input key be passed in - this is what is will be used to pass into the retriever. If this is NOT a subclass of BaseRetriever, then all the inputs will be passed into this runnable, meaning that runnable should take a object as input.
