Who in the world uses spotlight search. If you don't know where things are on your mac, give up.
Apple has "hidden" the Network Utility in a folder buried on the hard drive verses having it in the actual Utilities folder you can access from the Go menu starting with Yosemite. Combine this with the hard drive no longer automatically appearing on the desktop and you make a nice problem for people trying to do tech support and walk something through pingtesting. Spotlight is the only easy way to get it now.
