Hi, That's what we discussed the other day on irc. It doesn't do more than "use map view function to filter changes instead of duplicating the effort in writing a filter function that does the same, which is apparently done a lot. So each time a value could be emitted, a change is returned. The url is : http://127.0.0.1:5984/testdb/_changes?filter=_view&view=dname/viewname On other advantage is that I can also use this in an external indexer. - benoît.
