Yes, possibly I solved your problem rather than answered your
question. If you want to know if a particular term exists in the
database or not, use Xapian::Database::term_exists(). That's painful
by comparison with just doing what I suggested to get all the URLs
that have been indexed out (unless you already have a rig for deciding
whether to add a particular document or not).

(scriptindex may just use replace_document(), I can't actually remember.)
