I have a required custom field where users put an ID related to another service while they can have any forum name they want. I'd like to be able to search for users with a certain custom field entry so I can find their forum account associated with their ID.
This is how the custom field looks. I changed it to say ausername to prevent giving out too much info. (Same results with every kind of name/word I've tried.)
If I search for ausername, it says "No users matched the specified criteria."
