I get Facebook results, but nothing from my computer.
If I open a terminal and use 'locate' then I can find stuff, but the picture lens is empty.
Note that my picture files are on an NTFS partition. I have made a link named 'Pictures' in my home folder that points to the location where the picture files are. Again, this works with the 'locate' command and it also works for the Music lens, which is also a link in my home folder.
It also (kinda) works for the Video lens, though it only wants to find videos I have opened, which seems not consistent with the other lenses. (and also not very useful this way)
