java - Elasticsearch 将多个字段与 AND 运算符匹配不起作用

Question

我正在尝试使用 AND 运算符从具有多个字段的 elasticsearch 中获取文档

对于下面的查询，我期望得到以下结果

AB-7000-8002-W

但我收到此错误消息 Unrecognized token 'get': was expecting ('true', 'false' or 'null')\n at [Source: org.elasticsearch.transport.netty4.ByteBufStreamInput@40d2a7e8 ;行:1，列:5]

 get my_index12/_search {
    "query" : {
        "bool": {
            "should": [
                {
                    "match": {
                        "code": {
                         "query": "AB-5000-6002-AK",
                         "operator": "and"
                        }
                    }
                },
                {
                    "match": {
                        "locale": {
                         "query": "en_US",
                         "operator": "and"
                        }
                    }
                }
            ]
        }
    }
 }

请在下面找到我的索引文件

 {
        "_index": "my_index12",
        "_type": "doc",
        "_id": "2",
        "_score": 1,
        "_source": {
          "code": "AB-7000-8002-W",
          "locale": "en_US"
        }
      },
      {
        "_index": "my_index12",
        "_type": "doc",
        "_id": "4",
        "_score": 1,
        "_source": {
          "code": "AB-7000-8002-W",
          "locale": "en_EU"
        }
      },
      {
        "_index": "my_index12",
        "_type": "doc",
        "_id": "1",
        "_score": 1,
        "_source": {
          "code": "sG66tsdF",
          "locale": "en_US"
        }
      },
      {
        "_index": "my_index12",
        "_type": "doc",
        "_id": "3",
        "_score": 1,
        "_source": {
          "code": "AB-7000-6002-WK",
          "locale": "en_EU"
        }

只需将 get my_index12/_search { 行中的花括号移动到下一行。 它应该有效。

为了获得同时满足这两个条件的结果，您必须使用must 子句而不是should。 match 查询中的“AND”运算符不适用于您想要实现的用例。使用以下查询。

{
"query": {
"bool": {
  "must": [
    {
      "match": {
        "code": {
          "query": "TE-7000-8002-W",
          "operator": "and"
        }
      }
    },
    {
      "match": {
        "locale": {
          "query": "en_US",
          "operator": "and"
          }
        }
      }
     ]
    }
  }
}
