You can't use a custom stemmer in place of a Xapian::Stem object currently
- there's an experimental patch which allows this in ticket #186, but that
couldn't be easily wrapped by SWIG so it has been left for now:

You can just split the text into words yourself, stem them with your own
algorithm, and then add them using Document.add_term() or
Document.add_posting().

How does it compare to Snowball?
