elasticsearch - Elasticsearch在同一字段上查询多个条件

Question

这些是我的ES群集版本6.8中索引的示例文档(基于事件)

{
  "user_id": "user1",
  "account_id": "account1",
  "event_name": "event-1",
  "created_dt": "2019-09-30T08:40:42.297Z"
}

{
"user_id": "user1",
"account_id": "account1",
"event_name": "event-2",
"created_dt": "2019-10-30T08:40:42.297Z"
}

{
"user_id": "user2",
"account_id": "account1",
"event_name": "event-1",
"created_dt": "2019-10-30T08:40:42.297Z"
}

映射文件

{
"mappings": {
"properties": {
  "user_id": {
    "type": "text",
    "fields": {
      "raw": {
        "type": "keyword"
      }
    }
  },
  "account_id": {
    "type": "keyword"
  },
  "event_name": {
    "type": "text",
    "fields": {
      "raw": {
        "type": "keyword"
      }
    }
  },
  "created_dt": {
    "type": "date"
  }
}
}
}

我要完成的工作是动态获取在规定的时间使用event_name“event-1”和“event-2”的用户列表。

下方具有2的查询必须以同一字段“event_name”为条件，最终导致为空。

{
"query": {
"bool": {
  "must": [
    {
      "match": {
        "account_id": "account1"
      }
    },
    {
      "bool": {
        "must": [
          {
            "match": {
              "event_name.raw": "event-1"
            }
          },
          {
            "range": {
              "created_dt": {
                "gte": "2019-09-30",
                "lte": "2019-10-30"
              }
            }
          }
        ]
      }
    },
    {
      "bool": {
        "must": [
          {
            "match": {
              "event_name.raw": "event-2"
            }
          },
          {
            "range": {
              "created_dt": {
                "gte": "2019-10-30",
                "lte": "2019-11-05"
              }
            }
          }
        ]
      }
    }
  ]
}
},
"size": 0,
"aggs": {
"user_list": {
  "terms": {
    "field": "user_id.raw"
  }
}
}
}

获取所需存储段文档的理想方法是什么？可以使用IN和子查询在SQL中完成，但在ES中看起来并不容易

Answer 1

试试这个查询

GET my_index/_search
{
  "query": {
    "bool": {
      "must": [
        {
          "term": {
            "account_id": "account1"
          }
        },
        {
          "bool": {
            "should": [
              {
                "bool": {
                  "must": [
                    {
                      "term": {
                        "event_name.raw": "event-1"
                      }
                    },
                    {
                      "range": {
                        "created_dt": {
                          "gte": "2019-09-30",
                          "lte": "2019-10-30"
                        }
                      }
                    }
                  ]
                }
              },
              {
                "bool": {
                  "must": [
                    {
                      "term": {
                        "event_name.raw": "event-2"
                      }
                    },

                      "range": {
                        "created_dt": {
                          "gte": "2019-10-30",
                          "lte": "2019-11-05"
                        }
                      }
                    }
                  ]
                }
              }
            ],
            "filter": {
              "term": {
                "event_name.raw": "event-2"
              }
            }
          }
        }
      ]
    }
  },

  "aggs": {
    "user_list": {
      "terms": {
