Can someone explain to me the mystery of the Query Norm?

I have two Date Histogram Queries built using a DisMaxQuery over a  
Constant Score Filter that I think should produce IDENTICAL results.

In one case, the DisMaxQuery uses one Filter. In the second case, the  
DisMaxQuery has a second Filter that produces NO results. So why do  
the scores differ? Because Lucene/ES applies a "Query Norm" factor to  
the scores.

Here are the queries and their results! Is there a way to set the  
Query Norm to be 1.0? Thanks!
