The DBus interfaces are the best place to start for this I would say. If 
you use d-feet:

  https://fedorahosted.org/d-feet/

You can see all the interfaces Tracker makes public and use the API that 
way. In particular you are probably interested in the service:

  org.freedesktop.Tracker

and the interface:

  /org/freedesktop/Tracker/

using the method:

  SetBoolOption

If you use the string:

  Pause

You can control if the whole stack is paused or not.
The tracker-applet also does this using the context menu in the 
notification area.

For a list of all DBus interface signals and methods, see the 
introspection XML files in:

  data/dbus/*.xml
