Files and folders search doesn't work properly with Nautilus 3.30 from the GNOME 3 Staging PPA

[Marco Missere]

On my Ubuntu 18.10 I upgraded Nautilus from the GNOME 3 Staging PPA. But with Nautilus 3.30, when I try to search my files and my folders from the activity view, I almost never get results. With Nautilus 3.26 the files and folders search works flawlessly, but with Nautilus 3.30 does not work properly neither with Tracker 2.0.3 nor with Tracker 2.1.3 from the GNOME 3 Staging PPA.
