Enable Searching by domain of email address, either specifically by domain, or by allowing ~ operator w/reporter field

Problem Definition

Currently , there's no way to filter issue using email domain . It can often be helpful to search for all issues reported by a reporting user's email domain, perhaps not so much w/AOL or gmail, but certainly with corporate domains. Please enable either the contains operator for reporter or add a function to get email domain from reporter or similar solution.

Suggested Solution

Provide a JQL query , for example :-

reporter in emaildomainOf("customer1.com") ...
