Conditional filtering with AND ?

Trying to determine from what I'm getting out of the API basics material if/how it would be possible to format an AND like filter... e.g., let's say I want to find all User objects in my system that have an email that follow the pattern, {user}.somecompany@somedoman.com : I want to perform a filter that finds all users that have an email address that contains both somecompany AND somedomain.com How? I'd like to avoid having to do extra filtering on the client side (by getting all users with an email that contains somecompany and then filtering out the returned set of those that don't have the somedomain.com domain). thanks.
