CouchDb, как показать данные внутри массива и суммировать это?

Question

Я использую CouchDb и хочу создать представление, в котором я хочу подсчитать количество голосов на партию в моих документах.Я не могу даже показать все партии, он показывает только 3 случайные партии после того, как я запустил функцию, которую я перечислил ниже.

Как мне подсчитать голоса от каждой партии?

Документ в CouchDB:

            }
          ]
        },

          "teams": [
            {
              "party": "xd",
              "vote": "50"
            },
            {
              "party": "zh",
              "vote": "50"
            },
            {
              "party": "gh",
              "vote": "50"
            }
          ]
        }
      ]
    }
  ]
}

Что я хочу:

Key   | Value
-----------------------------
xd    | 300  
zh    | 300      
gh    | 300
sd    | 100          

Что я пытался использовать ине работал:

function (doc) {
var i;
  for( i=0; i < doc.Projects.length; i++){

  emit(doc.Projects[i].overview[i].teams[i].party,1);

  }
}
