And we are talking here exactly about the case where someone doesn't
have any local domain and no name resolution for the hosts on the LAN
because there is a caching-only name server in use, so I said that the
search option might not be wanted.

If you do have a local domain and named configured accordingly, there
isn't any overhead from specifying the search option, is there?
