Multihop Reasoning / Q&A with chat-bison

[datapiper-steve]

As the title suggests, I am looking for some examples that demonstrate the implementation and use of multihop Q&A with chat-bison.  At each hop, the agent will be using RAG (Retrieval Augmented Generation) - our RAG implementation has already been built.  I am looking for pointers on implementing multihop reasoning specifically using chat-bison.

Thank you in advance.
