Is it possible to search for employees based on their bank account number?

Summary:

Customer requires to search for employee based on their bank account information.

Has anyone had a similar requirement and was able to achieve it? I don't think this is standard Oracle (at least I could not find anything to setup via Search Views for My client groups person search) but maybe someone had a similar need, and can help.

Would it be feasible to do this via global search,if my client groups person search would not be feasible?

Thanks!
Kind regards,
