[Tracker] Remove index

["Andrea Caccin" <thekingcatch gmail com>]

Hi at all,
my name is Andrea Caccin and I have a little problem with indexing in
Tracker 0.5.4: I'd like to know if it's possible to completely remove
all indexes created in previuos configuration using command "trackerd".
Where does Tracker allocate the index in filesystem?

thanks in advance
