The problem is, if you have multiple sites, DNS is limited (at least in 
Linux/glibc) to 6 sub domains, after that, you're going to have problems. 
Better off with FQDN IMO.

        search Search list for host-name lookup.
               The search list is normally determined  from  the  local  domain
               name;  by default, it contains only the local domain name.  This
               may be changed by listing the desired domain search path follow-
               ing the search keyword with spaces or tabs separating the names.
               Resolver queries having fewer than ndots dots (default is 1)  in
               them  will  be attempted using each component of the search path
               in turn until a match is found.  For environments with  multiple
               subdomains  please  read  options ndots:n below to avoid man-in-
               the-middle attacks and unnecessary  traffic  for  the  root-dns-
               servers.  Note that this process may be slow and will generate a
               lot of network traffic if the servers for the listed domains are
               not local, and that queries will time out if no server is avail-
               able for one of the domains.

               The search list is currently limited to six domains with a total
               of 256 characters.
