That is currently not a feature, unfortunately. If you remember part of their name, you can log into the forums using the same username/password you use for the game and search here. "To match partial data use * as a wildcard."

(You don't actually have to log in but sometimes the search feature will prevent you from searching if you're not logged in and it's really annoying.)
