The data that is returned is the data that we are provided by each of the suppliers. The suppliers often provide us with their most searched for inventory, so what is returned is representative of what visitors are searching for across their sites. We don't control what each of them provides us with, we simply aggregate and distribute the data they provide us. The best approach for this will be to monitor actual live visitor behaviour, and if inventory gaps are identified, we'll provide guidance to let you liaise directly with the suppliers to get them to fill in any gaps. This is how we work on all integrations, and we find that most real searches have results returned.
