Reference documentation and code samples for the Discovery Engine v1beta API class Session.Types.Turn.
Represents a turn, including a query from the user and a
answer from service.
Output only. In
[ConversationalSearchService.GetSession][google.cloud.discoveryengine.v1beta.ConversationalSearchService.GetSession]
API, if
[GetSessionRequest.include_answer_details][google.cloud.discoveryengine.v1beta.GetSessionRequest.include_answer_details]
is set to true, this field will be populated when getting answer query
session.
public MapField<string, string> QueryConfig { get; }
Optional. Represents metadata related to the query config, for example
LLM model and version used, model parameters (temperature, grounding
parameters, etc.). The prefix "google." is reserved for Google-developed
functionality.
