Pat -

Wouldn't that be equivalent to giving the "name" field a higher
weight?

I think that at this point, the best way for us to get exact name
matches back first will be to use the phrase searching, and do two
searches, one for a phrase, and one regular.  But I will argue against
the overhead this would cause, so I guess we're just going to punt on
this requirement.  :)

Thanks for your help and thoughts on this.
