In the main menu on the right side of the screen, at the bottom you will find the global Search feature. This will allow you to quickly search for someone across Risk, Verify, and Alerts.
You can search for someone using these terms:
Name (first, last, or full)
Email address
Date of birth
Address or postcode
On Windows you can use the keyboard shortcut Ctl + S to open the search from anywhere in the app. On Mac you can use ⌘ + S.
