Hmm, this returns two matches, but neither seems to have "commistion" in
(or anything which might stem to it).

Probably it's this issue:

http://trac.xapian.org/ticket/225

I'm puzzled by the two apparent matches, but if there was a word with the
same stemmed form as "commistion" in those documents you would see this
behaviour, so I guess it is there but in some text not visible in the
view shown.
