How to Restrict Search Results and Prevent Access to Backend Views in ServiceNow?

[satyams10275267]

I am working on a requirement in ServiceNow where I need to restrict users from accessing the backend view of a request record when they search for its request number.

Currently, when a user enters a request number (e.g., REQ0013699) in the search bar, it redirects them to the detailed backend view of the request. However, I want to achieve the following:

1. Ensure users can only see requests they are authorized to view (e.g., their own requests).
2. Redirect the search result to a user-friendly view or a filtered list of requests instead of the backend details.
3. Administrators should still have access to the backend view for troubleshooting purposes.

I have explored ACLs, Search Sources, and custom views but need guidance on the best approach to achieve this without breaking the existing functionality.

Can someone provide step-by-step guidance or best practices to configure this in ServiceNow?
