I suggest introducing a functionality where users can request to be notified about updates or answers related to their queries. For instance, if a user asks about an upcoming event, such as the date of the next Apple event, and the information is not currently available, they could have the option to request a notification when the information becomes available.
How It Would Work:
1. User Request: When a user asks a question for which the answer is not yet known, they can opt to receive a notification once the information is updated.
2. Tracking and Notification: The system would track such queries and automatically notify the user via their preferred method (e.g., email, in-app notification) when the answer or relevant update is available.
