Comment(by robe):

 Hmm well it should be doing some matching with misspellings since it uses
 soundex.  However trigrams seem to be a bit better for matches in some of
 these kinds of cases.  If its a common issue with spaces perhaps we can
 get rid of spaces as a secondary soundex (as a hot fix).

 We were hoping to integrate trigram functionality in there to augment some
 of that fuzzy matching and also to improve on speed since GIST on trigram
 seems to be a bit faster than gist on soundex (and much improved with KNN
 GIST in 9.1). I'm not sure when we'll have time to get to that though.
