Comment 1 for bug 728961

Could be related to the fact that the daemons don't update their models if you set the same search string twice. And I really don't want to change that behaviour if I can avoid it. It's a really good measure against spamming clients (unity-mutter I am looking at you ;-)).

This may be further complicated by the fact that if you type a string that's an extension of the previous search then the places only removes the results from the existing result set. So consider:

 1) User types 't'. Daemons update models. Unity reflects that.
 2) User hides Dash with <super>
 3) User opens Dash again
 4) User types 'term'. Daemons narrow down result sets. Unity only sees row-removed signals => confusion?
