-----------------------------------------
Maybe I miss something but what is the usecase of this query? I guess you have a good reason for adding this patch - could you please add some documentation to the class and / or to this issue which explains what you are trying to do?

--------------------------------------
Just return null from Weight.scorer() and you can remove the NoHitsScorer.
Of course, one could always just use
this_field_doesnt_exist:foo
or from java code, something like
new TermQuery(new Term("-","-"))
