KS doesn't have it in core, and I don't plan to add it.  It's slow  
and icky in Lucene, too -- compared with everything else.  Because  
people don't automatically guess that such would be the case or  
understand why it's the case, some inevitably end up with unforeseen  
performance challenges.  Talking these people down on the mailing  
lists consumes a fair amount of energy.

In absolute terms, wildcard searching can be quite quite useful and  
performance can be acceptable for smaller collections.  It would be a  
nice thing to have on CPAN under the KSx namespace.  As a separate  
distribution, people would be psychologically prepared for behavior  
unlike that of the KS core.
