Returns Required. The ID of the search session. The session_id can be combined with Dialogflow V3 Agent ID retrieved from conversation profile or on its own to identify a search session. The search history of the same session will impact the search result. It's up to the API caller to choose an appropriate Session ID. It can be a random number or some type of session identifiers (preferably hashed). The length must not exceed 36 characters.
