elasticsearch - Elasticsearch:匹配嵌套对象的数组

Question

该示例摘自Elasticsearch引用:https://www.elastic.co/guide/en/elasticsearch/reference/5.3/nested.html

我的索引与此类似。唯一的区别是user.first和user.last是关键字类型，因此我可以对它们使用过滤器。

PUT my_index
{
  "mappings": {
    "my_type": {
      "properties": {
        "user": {
          "type": "nested" 
        }
      }
    }
  }
}

PUT my_index/my_type/1
{
  "group" : "fans",
  "user" : [
    {
      "first" : "John",
      "last" :  "Smith"
    },
    {
      "first" : "Alice",
      "last" :  "White"
    }
  ]
}

在两种情况下，我应该使用什么查询来获取与上述数组匹配的文档(恰好是两项，一项是John Smith，一项是Alice White):

顺序无关紧要

订单很重要

Answer 1

搜索后，获得Order的最佳方法无关紧要:对Count字段建立索引。

另请:Elasticsearch Equal Exactly

原因是:

In Elasticsearch, there is no dedicated array type. Any field can contain zero or more values by default, however, all values in the array must be of the same datatype.
