I was trying to use the search box in the activities view to find my pdf files, but it doesn't work any more. I remember it working earlier. It shows applications, folders, contacts, but no files in the search results.
I installed the tracker-gui "desktop search", and that shows my files, so tracker is working correctly. Gnome documents seems to show my files too.
Is this a change in behaviour of the search box, or is it a bug (known?)
Hard to say unless you mention which version of GNOME. Particularly gnome-shell and gnome-documents.
