Hi,
unless you emit sth like [key2, key1] I don't think you can find by key2 for
any key1. Reason being the sort of the underlying b+ tree. However, you can
emit several times per doc.
List functions to filter ex post yield crappy performance, so I'd never do
that. Sticking to several emits will rather do the trick I think.
Good luck
Sebastian
