在Elastic Search中对数组元素进行查询字符串搜索

Question

我正在尝试通过一个简单的示例应用程序学习Elasticsearch，该应用程序列出了与人相关的报价。映射示例如下所示：

{ 
  "people" : {
    "properties" : {
      "name" : { "type" : "string"},
      "quotations" : { "type" : "string" }
    }
  }
}

一些示例数据可能看起来像：

{ "name" : "Mr A",
  "quotations" : [ "quotation one, this and that and these"
                 , "quotation two, those and that"]
}

{ "name" : "Mr B",
  "quotations" : [ "quotation three, this and that"
                 , "quotation four, those and these"]
}

我希望能够对单个引用使用querystring api，并返回匹配的人。例如，我可能想查找报价包含（此与这些）的人-应该返回“ A先生”而不是“
B先生”，依此类推。我该如何实现？

编辑1：

安德烈（Andrei）在下面的回答似乎可行，数据值现在看起来像：

{"name":"Mr A","quotations":[{"value" : "quotation one, this and that and these"}, {"value" : "quotation two, those and that"}]}

但是，我似乎无法使query_string查询正常工作。以下没有结果：

{
  "query": {
    "nested": {
      "path": "quotations",
      "query": {
        "query_string": {
            "default_field": "quotations",
            "query": "quotations.value:this AND these"
        }
      }
    }
  }
}

有没有办法让query_string查询与嵌套对象一起工作？

Edit2：是的，请参阅Andrei的答案。

Answer 1

为了达到该要求，您需要查看嵌套对象，而不是查询平整的值列表，而是查询该嵌套对象中的各个值。例如：

{
  "mappings": {
    "people": {
      "properties": {
        "name": {
          "type": "string"
        },
        "quotations": {
          "type": "nested",
          "properties": {
            "value": {
              "type": "string"
            }
          }
        }
      }
    }
  }
}

值：

{"name":"Mr A","quotations":[{"value": "quotation one, this and that and these"}, {"value": "quotation two, those and that"}]}
{"name":"Mr B","quotations":[{"value": "quotation three, this and that"}, {"value": "quotation four, those and these"}]}

查询：

{
  "query": {
    "nested": {
      "path": "quotations",
      "query": {
        "bool": {
          "must": [
            { "match": {"quotations.value": "this"}},
            { "match": {"quotations.value": "these"}}
          ]
        }
      }
    }
  }
}
