Ah, searchlists. One of my pet peeves. I wish I could eradicate searchlists
completely from all resolver implementations. Why? As the man (page) says:
Most resolver queries are attempted using each
component of the search path in turn until 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. Also
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.
So if you want a wasteful, non-scalable, poorly-performing solution, use search
lists. If you want an efficient method free of any arbitrary restrictions, get
your users to form the habit of using fully-qualified names. It's what they have
to use for Internet email and Internet web browsing, so it's more consistent and
-- I would argue (and have successfully argued) -- more intuitive anyway. The
classic "too much typing" argument doesn't wash either, since this is the age of
point-and-click...
