Here's the man page for the tracker configuration file: http://linux.die.net/man/5/tracker.cfg

Here's the project page: http://projects.gnome.org/tracker

Now that i've read up on it, i'm more curious than ever at some of the options. AFAIK, there's no built-in global search capability in maemo, so all of the file content options in tracker configuration seem pointless, yet not disabled in the default tracker configuration. Does anyone know what use maemo makes of tracker's content indexing besides the very basic task of thumbnailing visual content?
