ElasticSearch should/must 子句未按预期工作

Question

下面是我的弹性查询

 GET _search
{
  "query": {
    "bool": {
      "must": {
        "match": {
          "marriages.marriage_year": "1630"
        }
      },
      "should": {
        "match": {
          "first_name": {
            "query": "mary",
            "fuzziness": "2"
          }
        }
      },
      "must": {
        "range": {
          "marriages.marriage_year": {
            "gt": "1620",
            "lte": "1740"
          }
        }
      }
    }
  }
}

返回的数据为 marriages.marriage_year= "1630"，Mary 为 first_name 最高 score.I 还想包括 marriages.marriage_year 在 1620 - 1740 之间，结果中未显示.它仅显示 marriage_year 1630

的数据

Answer 1

那是因为您有两个 bool/must 子句，而第二个子句在解析 JSON 查询时被删除。改为这样重写它，它将起作用：

{
  "query": {
    "bool": {
      "must": [
        {
          "match": {
            "marriages.marriage_year": "1630"
          }
        },
        {
          "range": {
            "marriages.marriage_year": {
              "gt": "1620",
              "lte": "1740"
            }
          }
        }
      ],
      "should": {
        "match": {
          "first_name": {
            "query": "mary",
            "fuzziness": "2"
          }
        }
      }
    }
  }
}

更新

然后你需要做不同的事情，在 bool/must 中你只需要 range 查询并将 match 移动到 bool/should 部分：

{
  "query": {
    "bool": {
      "must": [
        {
          "range": {
            "marriages.marriage_year": {
              "gt": "1620",
              "lte": "1740"
            }
          }
        }
      ],
      "should": [
        {
          "match": {
            "first_name": {
              "query": "mary",
              "fuzziness": "2"
            }
          }
        },
        {
          "match": {
            "marriages.marriage_year": "1630"
          }
        }
      ]
    }
  }
}
