Except that the search list is only supposed to be appended to qualified
names if lookups for the name as given fail, and both of the names he
mentioned exist.

www.schwab.com is delegated to what looks like a DNS-based load balancer
(like Distributed Director), with 15-second TTL, and when I tried looking
it up last week it was a little slow, so it's possible that he got a
timeout and then tried it with the search list.

But the other domain he mentioned in the original post looked pretty normal
when I tried it.
