I played around with the stopword filtering build into xapian, but it didn't turn out very well. Xapian first of all only calls the Stopper if there is also a Stemmer installed - and a no-op stemmer doesn't seem to satisfy this.
Next and bigger problem is that Xapian still indexes the unstemmed form of the stopwords meaning that the query for 'to' still scores the sentence "In order to work..." higher than "Tomboy".
I've tweaked the rankings a bit to solve this with pure ranking - but keeping this bug open since we might as well get the stopwords working at some point.
