Bug Description

When I frequently select a particular application in Unity's application search interface, I expect that application to appear at the top of subsequent matching searches. For example, suppose that I press the Super key and then type "trans" into the search box. On my system, the following three options appear, in order:

1. Arista Transcoder
2. Transmission BitTorrent Client (Qt)
3. Handbrake

I almost always select Transmission from this list, yet the search always returns Arista as the first result. I would expect that after a few times launching Transmission and not Arista, Unity would learn to present Transmission as the first choice, just like Gnome-Do, Kupfer, Quicksilver (Mac), the KDE Alt+F2 dialog, and others. This would seem to be a great use case for Zeitgeist.

-------------------------------------------------
Desired Solution:

Currently in the Dash relevancy ranking uses the quality of the string match, e.g. exact matches are ranked higher than partial matches, etc... Currently when the relevancy is the same e.g. there are two exact string matches, the results are then ordered A-Z

The change request is to change this second tier of ranking to be based on usage, e.g. when there are multiple exact matches, within the exact matches the results should be ordered based on frequency of use.

Omer, why is this incomplete?

Dash should learn from a user's actions. It doesn't make sense to type first 3 or 4 letters all the time you want to launch an app even after using unity for months. Dash should understand which apps I use the most and should promote them in search. If I open firefox a more than anything then I should be able to launch fire by the following combo,

   super > f > enter

and firefox should open. Why do I have to punch in "fire" all the time to start it?

I think you are quite aware of how bugs are handled in Unity, unless we get design input on this bug the status will be incomplete... Hint: affects ayatana-design.
