My system has this:
$cat /etc/resolv.conf
search myweb.com
nameserver 171.70.168.183
nameserver 2.2.2.2
But when I booted my system(actually in pristine condition) this search line with myweb.com wasn't present.
Did the DNS server add it?
And if it did add it then why didnt all the hosts connected to the same DNS get that search param? It happened only on a few.
