It can currently be hard to figure out why applications are showing up in search results.

 - We should highlight the matched text in some fashion (bold, like Google search results is probably good)

 - It would be good to try and always show the match and not ellipsize it out of existence. This is actually pretty hard to do well. Would require C code that dug into the PangoLayout, etc. But since most of our descriptions aren't longer than twice the available space, there's a quick hack - see if the match is in the first half or second half of the string and set the text item to ellipsize a the end or the beginning.

 - If the match is on something that we aren't currently showing (like a menu category - see bug 596436) we should show it. Not sure how to squeeze it in best - replacing the description is probably a bad idea. For category maybe - if it's the match - add it after the name with a dash 'Iagno - Games'.
