The 'create' parameter to InvIndexer's constructor has been removed in  
0.20_xx, and because KinoSearch validates all parameters, you get an  
exception rather than silent failure, exactly as intended.

Yes, they're supported in both the stable branch (0.1x) and the dev  
branch (0.20_xx), but the API has changed.  In the dev branch, you do  
something like this if you want to update an index...

   my $invindexer = KinoSearch::InvIndexer->new(
      invindex => MySchema->open('/path/to/invindex'),
   );

... as opposed to this, which starts fresh:

   my $invindexer = KinoSearch::InvIndexer->new(
      invindex => MySchema->clobber('/path/to/invindex'),
   );
