Simple retriever that applies an LLM between the user input and the query pass the to retriever.

It can be used to pre-process the user input in any way.

The default prompt:

DEFAULT_QUERY_PROMPT = PromptTemplate(
    input_variables=["question"],
    template="""You are an assistant tasked with taking a natural languge query from a user
    and converting it into a query for a vectorstore. In this process, you strip out
    information that is not relevant for the retrieval task. Here is the user query: {question} """
