elasticsearch Elasticsearch中嵌套数组的查询

我有一个对象，我想索引到Elasticsearch索引中。对象内的某些字段中有一个嵌套的JSON对象数组。例如：

"history":[
        {"color":"w","from":"g2","to":"g4","flags":"b","piece":"p","san":"g4","ts":{"$numberLong":"1586861525811"}},
        {"color":"b","from":"e7","to":"e5","flags":"b","piece":"p","san":"e5","ts":{"$numberLong":"1586861527710"}},
        {"color":"w","from":"f2","to":"f4","flags":"b","piece":"p","san":"f4","ts":{"$numberLong":"1586861531620"}},
        {"color":"b","from":"d8","to":"h4","flags":"n","piece":"q","san":"Qh4#","ts":{"$numberLong":"1586861533363"}}
        ],

"history":
        {"color":"w","from":"g2","to":"g4","flags":"b","piece":"p","san":"g4","ts":{"$numberLong":"1586861525811"}}

我用于此字段的映射是：

{
  "mappings": {
    "properties": {
      "history" : {
        "type" : "nested",
        "properties": {
          "color": {"type" : "keyword"},
          "from" : {"type" : "keyword"},
          "to" : {"type" : "keyword"},
          "flags" : {"type" : "keyword"},
          "san" : {"type" : "keyword"},
          "ts" : {
            "type" : "nested"
          }
        }
      }
    }
  }
}

我面临的问题是，当我将对象放入索引时，如果历史字段中存储了多个对象，则映射将不起作用。在Kibana中，历史记录字段存储如下：

{
  "color": "w",
  "from": "g2",
  "to": "g4",
  "flags": "b",
  "piece": "p",
  "san": "g4",
  "ts": {
    "$numberLong": "1586861525811"
  }
},
{
  "color": "b",
  "from": "e7",
  "to": "e5",
  "flags": "b",
  "piece": "p",
  "san": "e5",
  "ts": {
    "$numberLong": "1586861527710"
  }
},
{
  "color": "w",
  "from": "f2",
  "to": "f4",
  "flags": "b",
  "piece": "p",
  "san": "f4",
  "ts": {
    "$numberLong": "1586861531620"
  }
},
{
  "color": "b",
  "from": "d8",
  "to": "h4",
  "flags": "n",
  "piece": "q",
  "san": "Qh4#",
  "ts": {
    "$numberLong": "1586861533363"
  }
}

未填充我在映射中指定的不同嵌套字段

我的映射有问题吗？如果“历史记录”字段只有一个对象，则该选项似乎有效，例如：

"history":[
        {"color":"w","from":"g2","to":"g4","flags":"b","piece":"p","san":"g4","ts":{"$numberLong":"1586861525811"}},
        {"color":"b","from":"e7","to":"e5","flags":"b","piece":"p","san":"e5","ts":{"$numberLong":"1586861527710"}},
        {"color":"w","from":"f2","to":"f4","flags":"b","piece":"p","san":"f4","ts":{"$numberLong":"1586861531620"}},
        {"color":"b","from":"d8","to":"h4","flags":"n","piece":"q","san":"Qh4#","ts":{"$numberLong":"1586861533363"}}
        ],

"history":
        {"color":"w","from":"g2","to":"g4","flags":"b","piece":"p","san":"g4","ts":{"$numberLong":"1586861525811"}}

但对于多个对象，它无法正确映射。可能有什么问题？

您好，我很抱歉，您的映射没有任何问题。如何为这些数据编制索引？我认为你的问题在于索引部分，我使用Kibana中的控制台将对象放入我创建的索引中。
