Hi Olafur, This feature only allows you to write your code once, instead of both view and filter, even if they're the same code actually. The evaluation for views or filters currently is still separate. Ideally, replication, views, and filters would be able to share a common index (the view) and thus avoid any evaluation effort for processing. Once the view was updated, you'd just ask couch to "gimme any docs that match *** in the view" and then internally couchdb would refer back to the already calculated view. Sorry my explanation isn't better but I hope that clarifies the difference! A+ Dave
