> Here's a patch that disables Similiarty.coord() in the scoring of most
> automatically generated boolean queries.  The coord() score factor is
> appropriate when clauses are independently specified by a user, but is usually
> not appropriate when clauses are generated automatically, e.g., by a fuzzy,
> wildcard or range query.  Matches on such automatically generated queries are
> currently penalized for not matching all terms.
