How to stop gnome trackers

Stop trackers, tracker-filesystem-miner, tracker-store, zeitgeist-datahub  in Fedora by typing disabling them using and unchecking the items you want to disable on startup:
$ gnome-session-properties <enter>

Uncheck the items:
Tracker File System Miner
Tracker Miner for Flickr
Tracker Store
At present, these are checked by default.

This way, you would not have the trackers enabled and collating all kinds of metadata, document information and the like.
