When I do code searches in RubyMine, I sometimes want to only see non-test code for various reasons, such as knowing how often a particular method is used in our code base to judge adoption level. Normally, I would have to select each directory and run a code search one at a time, or search all directories at once and carefully skip over all test code while scrolling through the list. In a Rails app, directories that contain non-test source code could include app/, domain/, lib/ and even more.

There is a better way! The RubyMine Search tab has a toggle that will let you group source code search by Production and Test code. All you have to do is press this toggle and voila!
