Searching email address by typing address name, no domain
Hello. I have to ask because I have not found an answer here. How to search for an email address if I type only the name of the address, not its domain. So, if I want to serch for firstname.lastname@example.org, how do I just type mauronavarrog and perform the search. I know how to use the "==", how to place the address within quotes. Some other times I need to search by domain but do not know the name, like from people on the same company. How can I search, for instance, for @gmailcom and get all users with gmail. I appreciate the help.
