Beagle search ability is great. But the lack of search based on partial filename seems to be a serious deficiency to me.

I tried Beagle on and off for few months now, and I always have to go back to use "locate" 90% of the time. In statistical terms, I would say locate is not specific, but it is very sensitive. Which means yes there is plenty of wrong answers but it - almost - always contain the rigth one.

I think it is more important to be sensitive than specific for Beagle to gain momentum.

Search about content is a great evolution of search tool but filename will still remain the more likely element the user will remember - at least partially.

Example :
I have a file named : myapplication.pdf

query with "application" or "myapp" should return a hit even if the word "application" or "myapp" are not in the document.
