I.e., if the first query is "How did Alphabet do in 2022?" # and the current query is "How about 2023?", the current query will # be interpreted as "How did Alphabet do in 2023?". # # Example #2 (coordination between /search API calls and /answer API calls): # 1. Call /search API with the auto-session mode (see below). # 2. Call /answer API with the session ID generated in the first call. # Here, the answer generation happens in the context of the search # results from the first search call. # # Auto-session mode: when `projects/.../sessions/-` is used, a new session # gets automatically created. Otherwise, users can use the create-session API # to create a session manually. # # Multi-turn Search feature is currently at private GA stage.
