Hmmmm... If that's the case, would you suggest copying the relevant fields, using the different analyzers at index time? Then perhaps combining the two Queries returned from the MFQP into two clauses in a BooleanQuery? Or is there a more elegant way?
Because you're right of course, trying to use two different Analyzers on the same field(s) would produce...er..."interesting" results.
