The AND operator was added after I wrote that, I think. IN is the
default, NOT IN is also valid.

Note, the AND operator is *exceedingly* slow and should generally be
avoided, if possible. The SQL query that generates is not optimized at
present. It's there if you need it, but make sure it's not something
you do often, or try to cache the results for a time, or something
along those lines.
