Are the DOC ids sequential? Or just unique and ascending, I'm thinking like
a good little Oracle boy, so does anyone know?

If you know the id of the last document in the index.
(I don't know what's the best way to get it)
you could probably use a range query.
something like find all docs with the id in [lastId-100 TO lastID]. maybe
you should make sure that the first limit is non negative, though.

just a thought
