I'm only concerned about whether a UA is a robot or not, so
a "partial match" on a list of keywords is fine.  The actual UA
name is saved in the Apache access_log file, so I could examine
and report on individual names later, if I really wanted to.

Indexing is extremely important.  If you're using MySQL, PostgreSQL
or similar then you'll need to create indexes that are appropriate
to the queries you want to perform.  Database indexes are maintained
by, and administered from within, the the database engine.

Each domain should have its own <VirtualHost> block in the Apache
configuration.  If you have this already then you could log hits to
each domain to an individual log file.

If you don't like multiple access_log files, for some reason, then you
can use the "%v" token, with Apache's LogFormat directive, which will
expand to the virtual host name.

Most logfile analysers can handle log files that contain records from
multiple virtual hosts, or you can use something like "split-logfile"
to split the logfile by virtual hostname.

A couple of Google searches will scare up some useful information.
