     * `'ok'`: Returns results immediately, even if they're out-of-date.
     * `'update_after'`: Returns results immediately, but kicks off a build afterwards.
 * `options.update_seq`: Include an `update_seq` value indicating which sequence id of the underlying database the view reflects.
+* `options.partition`: If you query a couchdb database with the http adapter and a partitioned index, you need to add the partition key.
