From a user perspective, being able to copy/paste or type any formatted phone number would be much easer and make the contacts search page more user friendly. For example, manually typing or pasting the standard (123) 345-5678, 123 345 6789, 123.345.5678, 1234567890 or any other permutation should permit a search and return the user account information. It should be immaterial which method the user employs, the script should automatically remove any unnecessary characters and formatting so that any alphanumeric combination containing 10 digits yields search results. At present, when spaces or alphanumeric characters are used, the page does not produce an error, it simply doesn't work. A simple server-side validation script can do this without requiring a JavaScript OnSubmit script on the form itself. I'm using the MS Edge browser Version 145.0.3800.97 on Windows 10.
