MongoDB Atlas Search index creation question

I am trying to implement a search function using mongo db atlas search.

For example, assuming I register user information

  1. User information will be entered and code will be written to create the index.

  2. Driver connection

  3. Run the file using CLI

This is similar to the structure for creating an Atlas Search index.

What I’m curious about is if there are 1,000 concurrent users, or if there are more or fewer users, do I need to enter the cli command every time one user registers?
