Comment 4 for bug 729013

Pasted anyway, because I hunted it out before MPT found the dup.

  unity-place-applications-0.2.36/src/daemon.vala

    private void populate_section_queries ()
    {
      /* XDG category names. Not for translation. */
      /* We need the hack for ALL_APPLICATIONS below because Xapian doesn't
       * like '' or '*' queries */
      section_queries.add ("NOT category:XYZ"); //ALL_APPLICATIONS
      section_queries.add ("category:Utility"); //ACCESSORIES
      section_queries.add ("category:Game"); //GAMES
      section_queries.add ("category:Network"); //INTERNET
      section_queries.add ("(category:AudioVideo OR category:Graphics)"); //MEDIA
      section_queries.add ("category:Office"); //OFFICE
      section_queries.add ("(category:System OR category:Settings)"); //SYSTEM
    }
