Introduce data tracking

[Th0rgal]

To enable detailed analytics on user engagement and app usage, we need to track each query made by users. This will involve storing a document in our MongoDB database every time a query is executed.

Implementation Details

• Data Structure: Each document stored should contain user_id and timestamp.
• Database: MongoDB will be used to store this data (we know it and it works well).
• Schema Example: { "user_id": "<user_id_here>", "timestamp": "<ISO_date_time_here>" }

Tasks

1. Backend Update:

   • Modify the query handling mechanism to include a step for data logging.
   • Ensure the logging process is efficient and does not significantly impact query response times.
   • Implement a simple and effective schema to facilitate easy storage and retrieval of query data.

2. Data Privacy Compliance:

   • Verify that this data collection process complies with our privacy policy and any relevant data protection regulations.
