Setting the legacy "domain" option adds the specified domain to the
search list, so to disable search list processing IMO the only
configuration option needed is

search .

To be honest I don't know what other stub resolvers are already doing.
I'm trying to address the case where the same query is performed
twice, once "as_is" and another one appending then "." domain that
effectively does not modify the original query.
