Hello, fallowing this recursive_

Hello, fallowing this recursive_retriever example https://docs.llamaindex.ai/en/stable/examples/query_engine/recursive_retriever_agents/ can I query composable retriever and route queries to multiple agents and not only to one? changing similarity_top_k=2 or more will query in the same time on more or I should use another technique ?

Plain Text

# define top-level retriever
vector_index = VectorStoreIndex(
    objects=objects,
)
query_engine = vector_index.as_query_engine(similarity_top_k=2, verbose=True)

This will retrieve and run 2 agents yes

another question, it is possible to put a subquery engine in front of this top-level retriever and base on subquestions trigger different agents to resolve the user query ?

JJeff

or there is a better technique to use when we require a multistep workflow approach ?

@Logan M it is possible to put a subquery engine in front of this top-level retriever ?

LLogan M

You can yea, just wrap the query engine above into a sub-question query engine

JJeff

do you have any example how I can do that ?

LLogan M

just make a query engine tool and give it to the sub-question query engine?

Plain Text

tool = QueryEngineTool.from_defaults(query_engine, name="...", description="...")

sub_question = SubQuestionQueryEngine.from_defaults([tool], llm=llm, verbose=True)
