This is also an issue affecting our organisation.

Allowing the business to manage their own customers' access without requiring an Admin is important to:

• be responsive to customer requests
• ensure access to the project is controlled

can expedite this fix for the bug.

username varies and can be very common and it's extremely difficult to differentiate.

can't expect to guess which is the correct username that is associate with the email address.

and not everyone has the ord admin role to check for the username.

Another example of an issue so easy to fix yet no one seems to care, it's just beyond ridiculous. But GIVE US MORE AI CRAP BECAUSE WE ASKED FOR IT, RIGHT?

I can't believe that 3 4 years later this is still an issue...

Hi Team, 

The workaround to check for users via the User admin panel does not work for us as we are not admins, and it does not make sense to ask admin to keep checking users for my project.. We need the search user by email functionality ASAP. This is a basic search. it does not make sense that if a username exist, search by email address is disabled.  If this functionality is not implemented, this will force us to move to another platform. This is when we are thinking about upgrading our Atlassian plan.

How has this not been fixed in literal YEARS ???

Managing Customers is a nightmare as soon as the numbers grow beyond two figures. If the search option is so buggy could you at least disable it rather than let me use it?

Update: I don't understand how this isn't getting more votes. I've just had my team spend 10 minutes trying to find a particular email address as the user's name and the email address shared no resemblance. 

Yup, obvious flaw. Need results based on both fields. Need to find all contacts of a business = need to search by domain name, search by name = for obvious reasons.

Impacts search UI here: https://<site>.atlassian.net/jira/servicedesk/projects/<project>/customers

If however, users have changed their name in addition to having an invalid email -  for example:

email: me@email.comdonotuse //invalid TLD
name: Jane Smith

then the search string 'me@email.comdonotuse' will not have a hit. 

THIS.   The rest of that comment is BS.  If your customer only has an email address, then you can find them by searching for part of that email address.   If your customer has a name, as in that example, then you can ONLY search on parts of the name.

It doesn't matter if the email address is a bogus TLD — that is a total red herring and it is unfortunate that the OP used that which let the Atlassian go off down the garden path.   Even if you have a totally legit email address, the Name field is the only thing that is searched.

This is a ONE LINE FIX.  I am convinced that Atlassian has fired anyone who has the smallest clue about software (or even where the software is located).   ABSOLUTELY MISERABLE development process.

Thanks d3601787b40c. 33 hours does sound long, if it's causing issues for your site, I would suggest finding help at https://support.atlassian.com/.
