嵌套数据couchbase的索引

Question

以下是我的数据

 {
      "VehicleTrip": {
           "departureTime": 1483176300000
      },
      "Orders": {
           "Order": [{
                "numberOfShops": 3,
                "customerTitle": "Mrs",
                "notes": ""
                "orderId": "3060_1"
           }, {
                "numberOfShops": 3,
                "customerTitle": "Mrs",
                "notes": ""
                "orderId": "3060_2"
           }]
      }
 }

我想为orderId创建索引。我的桶名称是Delivery

我试过

CREATE INDEX isched1 
        ON `Delivery` (DISTINCT ARRAY v.orderId FOR v IN `Orders`.`Order` END);

但没用。 任何人都可以帮助我获取上述数据的索引。

谢谢， 维奈

您的示例文档的Orders对象与VehicleTrip处于同一级别，而您的索引则视为VehicleTrip的属性。

如果您打算嵌套，您的文档应如下所示

{
     "VehicleTrip": {
          "departureTime": 1483176300000
     },
     "Orders": {
          "Order": [
          {
               "numberOfShops": 3,
               "customerTitle": "Mrs",
               "notes": "",
               "orderId": "3060_1"
          }, {
               "numberOfShops": 3,
               "customerTitle": "Mrs",
               "notes": "",
               "orderId": "3060_2"
          }]
     }
}

否则，您需要更新索引以匹配文档中的内容：

CREATE INDEX isched1 
    ON `Delivery` (DISTINCT ARRAY v.orderId FOR v IN `Orders`.`Order` END);
