Spotlight change keywords in Yosemite Spotlight seems to always suggest the wrong thing and doesn't learn when I don't choose the Top Hit.

Is it possible to change the priorities of Spotlight? The internet suggests that there has been a way to edit keywords (or Spotlight comments) under "right click/Get Info". But there is no such thing here in Yosemite anymore.
Preferences -> Spotlight -> Search Results allows you to change the order of results by reordering categories.  As far as specific items within a category, this answer suggests that Spotlight is supposed to learn the Top Hit from what you choose over time: Changing OS X Spotlight priorities for specific applications.
