Hi Josh
I'm no expert on how the ranking modes work, so I can't speak to your first
point. As to the second though - yes, you can't use any other match mode - but
you can use boolean syntax to get the same effect: 'foo | bar' in :extended2 is
the same as 'foo bar' in :any.
Not sure if it's worth having the discussion about ranking behaviour on the
Sphinx forum - it's all Sphinx internals.
Cheers
