Interesting. In Khoros JX community you can @mention a user and when you type in @email@example.com it will find a corresponding user if the partial email matches and allow you to @mention the user. It doesn't confirm the email address and changes to the username once you select it from the pop-up It's not necessarily "Searching" in the context mentioned above but is very valuable if you're trying to locate someone who's username has changed or they might have multiple accounts. for example firstname.lastname@example.org and email@example.com Definitely doesn't guarantee those two people are the same person but usually there are other indicators that corroborate that they are and then you can help the user focus on one account going forward if merging isn't possible.
