A quick grep shows that if "between" weren't a stopword, it would produce almost 600 hits in our core docs, most of which are not what you're looking for. So I concur with somebody's apparent decision to make it a stopword.
It is a standard stopword in the snowball stemmers we ship, sadly. I don't think we have an easy way to say "use this dictionary and it's stopwords, except these couple of words that we want to not be stopwords"? Other than having to maintain a separate copy of the whole file and then forgetting to update it?
