one other thing
sometimes the issue is consistent and I'll go days where the issue will persist, then all the sudden it will work and i'll see my recent docs in alfred.
right now all my recent docs are available in alfred - but i expect in a few hours that will change.
the only thing that i can think of that's differnet is that i recently rebooted (and i normally leave this mac running 24/7)
maybe there's something to that?
point is: sometimes it works, sometimes it doesn't. very odd...
