Debian Buster: Tracker GUI (tracker-needle) missing After upgrading from Debian Stretch to Buster I found that Tracker desktop search GUI (tracker-needle) was missing. How can I get it back? Please, don't suggest installing Recoll. I used to use it quite a while but its indexer was resource hog and I switched to Tracker.

Tracker no longer provides its own search interface; instead, GNOME applications such as Documents and Music will use its indexes for their search features. You can also search for file contents from GNOME Shell: open the “Activities” view and type your search query.

See the Tracker documentation for details.
