Paul - look at debugQuery=true output to see why scores end up the way they do.
Use the explainOther to hone in on a specific document to get it's
explanation. The math'll tell you why it's working the way it is. It's more
than just likely that some other scoring factors are overweighting things.
Also, now that I think about it, you'd be better off leveraging edismax and the
boost parameter. Don't mess with your main q(uery), use
boost=genre:Citation^0.01 or something like that. boost params (not bq!) are
multiplied into the score, not added. Maybe that'll be more to your liking?
