Actually DNS search would be your domain that would get appended to host
names that aren't fully qualified.

So if you put home.local in your search and then you try to ping a machine
named files, it'll try files and then files.home.local

So in search put your local domain name, or remove it if you don't have one.

Glad I could actually help,
