I just installed Natty fresh on my laptop, and for the purposes of this experiment, I have one file on my system. My Downloads, Documents, Music, etc are all empty, but Pictures contains one file named "tornado.png". If I simply hit the super key and search through that main lens, I don't get results for "to", "torn", or even "tornado" -- only for "tornado.png". And, if I search using the Files Lens (Super+S), I get no results at all, even for "tornado.png".
Is this not getting indexed properly? What's going on?
