man resolv.conf
search Search list for host-name lookup.
By default, the search list contains one entry, the local domain
name. It is determined from the local hostname returned by
gethostname(2); the local domain name is taken to be everything
after the first '.'. Finally, if the hostname does not contain
a '.', the root domain is assumed as the local domain name.
[...]
The domain directive is an obsolete name for the search direc‐
tive that handles one search list entry only.
Those lines do nothing, unless you routinely type commands like
"ssh lemon" or "ping pineapple" with no dots in the hostname. In that
case, assuming the hosts are not defined in /etc/hosts, the resolver
will try to look up "lemon.attlocal.net" or "pineapple.attlocal.net" or
whatever.
Remember that something will probably overwrite your changes to the
resolv.conf file, unless you take preemptive steps.
