"keywords" for Linux OS menu

[nger]

I installed Giada on Ubuntu with Gnome-shell. And I can find app in app's menu only by typing "Giada". No results for "mix, dj, music" etc.
For example Ardour has a lot of this kind of keywords for menu. I could be nice, if system could find Giada by searching mentioned keywords.

Hi nger, interesting feature. I guess it doesn't work right now because we didn't use the "comment" field in the desktop file. Added to our roadmap.
