Yes. Actually the terminology is "initial" and "update," so the
switch isn't really mislabeled. Of course you may want to include a
-a switch if you're updating...

Just scan through them? If it doesn't actually download anything more
or have to re-parse things, it's going to be pretty fast. The
installation on htdig.org currently has about 15,000 URLs and has to
index new mail messages mostly. The update usually takes a few
minutes. (It also has local_urls set, which helps a fair amount.)
In general, updates will be *much* faster than the initial dig.
