I was debugging a highlighting problem and noticed that when I included the word "are" in a search, Omega didn't return that word as a term. I can only assume Omega has a set of stop words. I did a search for xapian omega stopwords but didn't find a set defined anywhere. I see there are a few of them defined in query.cc when I look at the Omega source. I'm going to put a list of them on the xapian wiki so someone else looking might find them easier. Jim.
