Many thanks for the replies. Intuitively, I was hoping that this could be done with a single query class especially since ConstantScoreQuery seems to be made for that. I've seen the pattern of wrapping a BoostQuery around a ConstantScoreQuery but this seemed to me like a workaround. Anyways, I understand that finally this is a well adopted pattern so I am not going to insist more on this.
