I don't like adding more error-prone stuff like this. Giving folks
something that sounds really useful but blows up in many cases is
not a good idea. We should fix all of these before we add more, no?
I'm all for that. Since Yonik volunteered to take the first steps,
I'll follow his lead in refactoring these queries when he gives the
word.
I would be in favor of converting all of the term-expanding queries
to be constant-scoring. A filter class could easily be implemented
that takes a FilteredTermEnum. Combine this with
ConstantScoreQuery (from http://issues.apache.org/jira/browse/
LUCENE-383) to re-implement each term-expanding query class. What
do others think?
The downside is scoring closer matches (in say the WildcardQuery)
would no longer be possible, right?
