Can anyone explain the following behavior to me?

[jgreen at t-rex ~]$ nslookup proteome.hpcc.triad.local
Server:         127.0.0.1
Address:        127.0.0.1#53
Name:   proteome.hpcc.triad.local
Address: 10.2.149.1

[jgreen at t-rex ~]$ nslookup proteome.vlan88.hpcc.triad.local
Server:         127.0.0.1
Address:        127.0.0.1#53
Name:   proteome.vlan88.hpcc.triad.local
Address: 192.168.88.179

[jgreen at t-rex ~]$ nslookup proteome
Server:         127.0.0.1
Address:        127.0.0.1#53
Name:   proteome.hpcc.triad.local
Address: 10.2.149.1

[jgreen at t-rex ~]$ nslookup proteome.vlan88
Server:         127.0.0.1
Address:        127.0.0.1#53
** server can't find proteome.vlan88: SERVFAIL

My /etc/resolv.conf is:

[jgreen at t-rex ~]$ cat /etc/resolv.conf
search hpcc.triad.local
nameserver 127.0.0.1

I don't understand why it's not using the search field from  
/etc/resolv.conf for the second short name (proteome.vlan88).  Any  
idea what can I do to get this working?

Thanks,
