Comment 4 for bug 1222527

Ideally, Software & Updates would be just a panel in System Settings, not an app of its own. If so, by default it wouldn't show up in search results.

However, ideally top-level System Settings screens would show up in the search results anyway, so we'd be back where we started.

OS X addresses this problem in two ways: (1) Any "System Preferences" panels are in their own category, separate from "Applications", in search results. (2) They have generic toggle-switch icons, rather than the icons you would see inside System Preferences itself. <https://i2.wp.com/www.ostricher.com/io-content/uploads/2014/11/spotlight-launch-syspref.png> That avoids confusion between Bluetooth settings vs. the Bluetooth File Access app, Startup Disk settings vs. the Disk Utility app, etc.
