I would agree that searching on numbers is useful and it would be good to have functionality restored.
We add a form to tickets relating to purchasing to record the PO# and often will search for the PO# in the later week/months to find the ticket relating to something which has been finally delivered.
I tested the search out when I saw the commit but for some reason I thought it was working still for form fields. In some testing today though it does initally show an email address (correct for the ticket where the PO# is stored) but if you hit the search button it then doesn't show a result.
Using "####" does work correctly however.
If it is finding a result during the type-ahead functionality then I guess it isn't improving performance much for when the search button is later pressed ?
@shawn-knudsen A tip with using the advanced search is to enter your term then hit the looking glass symbol to do the search. If you hit enter or click on one of the search ahead results you usually end up with all tickets raised by the email address instead of the results of your search term.
