I also think it would be better to have a GetStatus method instead of an
IsBusy so it can return a string for each of the possible status.

For a client it might also be handy to know, if its indexing, the uri of
the entity being indexed. 

We will also need a dbus signal StatusChanged to be emitted too but that
can wait if you are busy
