Disable windows vista search auto wildcarding

GrimReaper

I'm wanting to search for all files that end with .ht, a simple enough search of *.ht should give me that but windows vista search is deciding to wildcard that, effectively searching for *.ht*. Is there a way with vista to tell it not to wildcard that?

Otherwise i'm getting a big fucking list of all browser cached pages etc. (htm, html etc)

EDIT: Ok, I suspect find partial matches under search options probably disables that.
