有没有办法只聚合某些嵌套文档

Question

我有一个像这样的文档，其中interactInfo是嵌套的Document。我需要单独找到标题（细分）的汇总，而不是标题（订单）的汇总

{
    "interactionId": "a26617a0-0530-4b41-9db6-4ca53e83e63e",
    "interactionInfo": [
      {
        "title": "segments",
        "value": "1"
      },
      {
        "title": "Order",
        "value": "2"
      }
    ]
  },
  {
    "interactionId": "a26617a0-0530-4b41-9db6-4ca53e83e63e",
    "interactionInfo": [
      {
        "title": "segments",
        "value": "4"
      },
      {
        "title": "Order",
        "value": "3"
      }
    ]
  }
]

这是我所做的汇总

 "aggs": {
    "InteractionInfo": {
      "nested": {
        "path": "interactionInfo"
      },
      "aggs": {
        "interactionInfoFilter": {
          "filter": {
            "term": {
              "interactionInfo.title.keyword": "segments"
            }
          },
          "aggs": {
            "SUM": {
              "sum": {
               "script": "Integer.parseInt(doc['interactionInfo.value.keyword'].value)"
              }
            }
          }
        }
      }
    }
  }

我对以上汇总的响应是

"aggregations": {
    "InteractionInfo": {
      "doc_count": 6,
      "interactionInfoFilter": {
        "doc_count": 0,
        "SUM": {
          "value": 0
        }
      }
    }
  }

我期望的是仅返回标题的总计（细分），即值必须为5，但返回0 还有其他方法可以找到仅针对标题（细分）的集合
