You can define your own stemmer by subclassing StemImplementation:

http://xapian.org/docs/apidoc/html/structXapian_1_1StemImplementation.html

So if you want to use an existing stemmer but handle some words
differently, just create a subclass which checks for the exceptions,
and passes all other words to the existing stemmer.

If there are words which are poorly handled by a particular stemmer,
it's worth letting us (or the snowball team) know too.
