Hi Vin
If you have an STI setup like below, the parent's index is shared with
the child class. Which means that the index defined in B is an
additional one... and I'll say right now that multiple indexes for a
single model needs some work (I need to clear up what Sphinx requires,
and then make sure the code enforces that).
As for the db:create thing, I'll try to get a patch sorted soon -
ideally this week.
Cheers
