nslookup/dig not finding short hostname convention

My configurations files on my DNS server (lnx03) below.

/var/named/my-zone.zone:
; Zone file for 192.168.0.x
;
$TTL 3D
@ IN SOA ns.lansys.com. hostmaster.lansys.com. (
200512051 ; serial number
8H ; refresh, seconds
2H ; retry, seconds
4W ; expire, seconds
1D ) ; minimum, seconds
;
NS ns ; Nameserver Address
;

lan4 A 192.168.0.110
lan3 A 192.168.0.111
lan5 A 192.168.0.112


/etc/hosts:

192.168.0.110 lan4 lan4.lansys.com
192.168.0.111 lan3 lan3.lansys.com
192.168.0.112 lan5 lan5.lansys.com

When I run:

ping lan4.lansys.com (works)
nslookup lan4.lansys.com (works)
dig lan4.lansys.com (works)


If I remove the hosts names from the /etc/hosts file

When I run:

ping lan4 (works)

dig lan4 (doesn't work)

I can't understand why the shorter naming convention doesn't work when
the name is present in the /etc/hosts file. Is the zone file
configured incorrectly?

Add a entry in /etc/resolv.conf
search <domain name>
domain <domainname>


then it will append domain name in each unqualified hostname

That be it. Thanks!
