I did a clean install of Quantal, and the first thing I did was add the gnome3-team/gnome3 ppa and install gnome-shell and nautilus 3.6. Nothing else, no messing around with the configuration settings or anything. Right out of the box, the search is broken. Terribly, annoyingly broken. It can only search file/folder names within the same directory. It doesn't search recursively or traverse down the file tree, so it won't find a matching file within a folder in the current directory. Is there a package that I'm missing to make this work? Is anyone else having this problem? This seems to be Ubuntu-specific...
