have the notion that there can be both a search list and a default
domain at the same time. The resolv.conf "domain" directive is now
used only if there is no "search" directive, and is treated exacly
like a one-element searchlist. The "+domain" option of dig and the
"set domain" command of nslookup are now merely ways of overriding the
resolv.conf search list. Parents of the name given in the "domain"
directive are still not searched; this is considered a feature and is
consistent with lwres, but different from the BIND 8 resolver. The
"+defname" option to "dig" is now deprecated and treated as a synonym
for "+search"
threads in BSD/OS and mistakenly attributing that to all platforms.
Added a couple of paras on how lookups are performed.
Documented the difference n how trunctaed responses are handled.
