Nik Everett commented on LUCENE-5245:
-------------------------------------
The query norm applied to the constant score query changes. Say I had a query
string like "foo:findm*^20 bar:findm*" and only foo had a result on shard 1 and
only bar had a result shard 2. Both end up with the same score because on
shard one the query is rewritten to "foo:findm*^20" (norm = .05) and
"bar:findm*" (norm = 1).
> ConstantScoreAutoRewrite rewrites prefix queryies that don't match anything
> before query weight is calculated
