The search string is easy "sendmail -group:comp.mail.sendmail".

It is "almost right" except:
1) I would like to limit "time span" of searches to 1 day or 1 week 
   [ extra as_qdr=d or as_qdr=w parameter in google URL ]
   It seems to require trivial change in  nnweb-google-search in nnweb.el
2) How to make the virtual group *permanent*?
   It "vanishes" quickly from groups buffer.
