xgoogle is unable to search using domain limiter: site:example.com

xgoogle is unable to search using domain limiter: site:example.com returning not results instead.

[gg4u]

Got the same issue.
Tried to replace in search.py
line 190:
#safe_url = [url % { 'query': urllib.quote_plus(self.query),
safe_url = [url % { 'query': urllib.quote('site:'+self.query),

but did not work either.

I could not find info @ google api either:
what is "site:" actually: an attribute, a keyword, a method?
I couldn't see any particular parameter in the query string ...
