NAME
resolver - resolver configuration file
SYNOPSIS
/etc/resolv.conf
...
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 following the search keyword with
spaces or tabs separating the names. Most resolver queries will
be attempted using each component of the search path in turn un-
til a match is found. 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 available for one of the domains.
The search list is currently limited to six domains with a total
of 256 characters.

I still think you're carrying along some mistake that you made decades
ago, which has simply never caused any problems, but is also not doing
anything beneficial.
This. Here's an extract from the oldest debian man page I know of for
this file (from 1995--and people complain about how up to date the
documentation is today!):
domain Local domain name. Most queries for names within
this domain can use short names relative to the
local domain. If no domain entry is present, the
domain is determined from the local host name
returned by gethostname(2); the domain part is
taken to be everything after the first `.'.
Finally, if the host name does not contain a domain
part, the root domain is assumed.
search Search list for host-name lookup. The search list
is normally determined from the local domain name;
by default, it begins with the local domain name,
then successive parent domains that have at least
two components in their names. This may be changed
by listing the desired domain search path following
the search keyword with spaces or tabs separating
the names. Most resolver queries will be attempted

The domain and search keywords are mutually exclusive. If
more than one instance of these keywords is present, the
last instance will override.
The last paragraph is why it's just odd, not problematic. The current
man page is basically identical.
