Subject [jira] Commented: (LUCENE-2270) queries with zero boosts don't work
Date Thu, 18 Feb 2010 14:11:28 GMT


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.
