db already has these facilities

we have volume table for UDI -> URI
http://svn.gnome.org/viewvc/tracker/trunk/data/sqlite-tracker.sql?view=markup


We have service stable for rest-:
services.AuxilaryID is to be used for link to Volumes.ID
Services.Enabled is used to indicate if hit is available (IE mounted)
http://svn.gnome.org/viewvc/tracker/trunk/data/sqlite-service.sql?view=markup


just need to tie it all together. 


Indeixng needs to be changed to set above and to enable/disable entries whenever relevant volume is 
mounted/unmounted.

All search sql needs to be adjusted to ignore hits when Enabled = False
