Right now I could only see the applications (frequent and all) and files in the home folder. But I can't see a file which is present in a folder in home directory. For example I can't see the files in Downloads folder in home directory but can see the folder Downloads and files present in home directory while searching in the Debian activity overview search bar (latest GNOME version). Also I am using Linux Mint 16 but the desktop environment I'm using is GNOME with mutter as window manager.
See files other than home folder files in activity overview seach bar in debian
debian;gnome
