Vivien closed LUCENENET-449.
----------------------------

    Resolution: Not A Problem

I figured out the new way of handling it.

> When WildcardQuery.Rewrite method is called, it calls ConstantScoreAutoRewrite.Rewrite
method.
> In this method, int docCountCutoff seems to be 0 for the cases I tested, therefore, docVisitCount
is usually greater than 
> docCountCutoff, as the result of this, the code block where // Too many terms -- make
a filter is executed.
> So if we have document (with contents "text cat and cut") indexed, we want to search
for c*t, if we set the initial query to have the search criteria c*t, then call query.rewrite(),
I am expecting to have the result query with criteria of searching for cat + cut.  Version
2.9.2 just returns the original wildcard query, which is not a correct behaviour if you look
at version 2.4.1.
