在 Elastic Search 中使用 And & OR 进行查询

Question

我是 Elastic Search 的新手，我有如下文件：

相同 JSON 索引的映射如下：

映射

{
      "mappings": {
        "properties": {
          "age": {
            "type": "long"
          },
          "hobbiles": {
            "type": "keyword"
          }
        
      }
    }
}

一些示例文件如下所示：

        [{
        "_id": "test@domain.com",
        "age": 12,
        "hobbiles": [{
                "name": "Singing",
                "level": "begineer"
            },
            {
                "name": "Dancing",
                "level": "begineer"
            }
        ]
    },
    {
        "_id": "test1@domain.com",
        "age": 7,
        "hobbiles": [{
                "name": "Coding",
                "level": "begineer"
            },
            {
                "name": "Chess",
                "level": "begineer"
            }
        ]
    },
    {
        "_id": "test2@domain.com",
        "age": 20,
        "hobbiles": [{
                "name": "Singing",
                "level": "begineer"
            },
            {
                "name": "Dancing",
                "level": "begineer"
            }
        ]
    },
    {
        "_id": "test3@domain.com",
        "age": 21,
        "hobbiles": [{
                "name": "Coding",
                "level": "begineer"
            },
            {
                "name": "Dancing",
                "level": "Football"
            }
        ]
    }
]

 

现在我想获取 id IN (test@domain.com, test1@domain.com) 和年龄大于 5 的文档。 [操作上] hobiiles Football。

我对输出的期望是我应该得到三个文档：如果爱好不匹配，那么它也应该没问题，但如果爱好匹配，那么该文档应该在最前面。基本上我想匹配爱好，但如果它不匹配它是可选的，那么我也应该根据先前的子句获取数据。

[test3@domain.com, test@domain.com, test1@domain.com]

测试 3 在顶部，因为 Football 在那里匹配，测试和测试 1 因为 age 和 id 匹配在那里。

Answer 1

这需要使用Should 子句。应该等价于“或”。因此，如果满足 should 查询中的任何一个条件，就会返回一个文档。

对于 id 和 age 的条件，我使用了 filter 子句。它相当于 "AND" 。过滤子句不计算匹配文档的分数，因此任何匹配“hobbiles.level”的文档都会排名更高。

询问

{
  "query": {
    "bool": {
      "minimum_should_match": 1, 
      "should": [
        {
          "term": {
            "hobbiles.level.keyword": {
              "value": "Football"
            }
          }
        },
        {
          "bool": {
            "filter": [
              {
                "terms": {
                  "id.keyword": [
                    "test@domain.com",
                    "test1@domain.com"
                  ]
                }
              },
              {
                "range": {
                  "age": {
                    "gt": 5
                  }
                }
              }
            ]
          }
        }
      ]
    }
  }
}

结果

  "hits" : [
      {
        "_index" : "index8",
        "_type" : "_doc",
        "_id" : "qE06noMBfFiM6spcUTo4",
        "_score" : 1.3112575,
        "_source" : {

          "age" : 21,
          "hobbiles" : [
            {
              "name" : "Coding",
              "level" : "begineer"
            },
            {
              "name" : "Dancing",
              "level" : "Football"
            }
          ]
        }
      },
      {
        "_index" : "index8",
        "_type" : "_doc",
        "_id" : "pE03noMBfFiM6spc4jr2",
        "_score" : 0.0,
        "_source" : {

            {
              "name" : "Singing",

            },
            {
              "name" : "Dancing",
              "level" : "begineer"
            }
          ]
        }
      },

          "age" : 7,
          "hobbiles" : [
            {
              "name" : "Coding",
              "level" : "begineer"
            },
            {
              "name" : "Chess",
              "level" : "begineer"
            }
          ]
        }
      }
    ]

Answer 2

特长;

它可以通过布尔查询来实现。

PUT /_bulk
{"index":{"_index":"73935795", "_id":"test@domain.com"}}
{"age":12,"hobbiles":[{"name":"Singing","level":"begineer"},{"name":"Dancing","level":"begineer"}]}
{"index":{"_index":"73935795", "_id":"test1@domain.com"}}

{"index":{"_index":"73935795", "_id":"test3@domain.com"}}
{"age":21,"hobbiles":[{"name":"Coding","level":"begineer"},{"name":"Dancing","level":"Football"}]}

      ]
    }
