For example, I want to display a list of movie genres that's derived from a list of movies. Many movies have the same genre. But I wanted a view that contained the keys that were the unique Genre names of all the movies in the database. That’s what the grouping feature of queries does. Set query.groupLevel=1 and the result will contain one row for every unique key. (See the docs.) The solution you posted isn’t going to work because the map block uses mutable external state, which isn’t allowed. In this case it looks like there’d be trouble if you deleted all the docs with a specific genre, then added another one with that genre; it wouldn’t emit anything. —Jens -- You received this message because you are subscribed to the Google Groups "Couchbase Mobile" group.
