I've always used Spotlight exclusively as an application launcher, and so I have disabled everything except Applications (and System Preferences) to clean up and speed up results. However, in Mavericks, it's now showing the "Other" category which brings up all kinds of stuff, depending on what I search for. It's not included in the Spotlight Preferences, so I can't seem to disable it. Is there a workaround to fix this? While we're at it, I wouldn't mind ridding of Web Searches as well.
tl;dr: How do I remove Other?
