Function to find applicant in ATS by email address

With many applicants using email addresses which don't always relate to their name and the people using the system not having much contact with the applicants other than via the hiring lead it can be difficult to find the correct applicants to update the records in the ATS. Being able to find an applicant by their email address would be the easiest way to improve usability. Not all users have access to the query option in the system either.
