Yonik Seeley commented on LUCENE-2270:
--------------------------------------

The problem is twofold: a query with only zero boosts on it's clauses results in a query norm of infiinity, and a normalization factor for the query of NaN (0*Inf).  This has always been the case.  But our new collectors cannot handle these score values and mess up - for example returning docids equal to the sentinal value Integer.MAX_VAL.
