mapreduce - How can I query by document attribute when the attribute is an array? -


in couchbase server 3.0, documents in bucket of form:

{ "id":"xyz", "categories":["news", "articles", "etc.etc.."]}

i want write view such when specify key="news", documents include "news" in "categories" array attribute returned.

i went far writing map function emits same article many times have elements in "categories" array. 

function (doc, meta) {   for(var = 0; < doc.categories.length ; i++)   emit(doc.categories[i], doc); }

but i'm stuck reduce.

turns out map function sufficient, needed query key="cateogoryname" in url.

i confused because if don't wrap key in quotes in query mysterious error, see: https://issues.couchbase.com/browse/mb-7555

not sure if reduce function more efficient though..
