Xapian::QueryParser currently normalises accents, so the u-umlaut is
normalised to "ue".  As you've noticed, this is a bit unexpected - where
such normalisation is the appropriate thing to do, it should really be
done in the stemmer itself.  I'm currently tying up loose ends for
0.9.3, then my plan is to address this along with merging the utf-8
patches and the latest snowball stemmers in a new major release.

Here's some previous discussion:
