elasticsearch - ElasticSearch中2个不同字段之间的日期范围

Question

我想根据开始日期和结束日期在两个日期之间获取文档。

这是映射:

PUT data 
{
  "mappings": {
    "_doc": { 
      "properties": { 
        "product_code": {"type": "keyword"},
        "color_code": {"type": "keyword"},
        "warehouse_id": {"type": "short"},
        "stock": {"type": "float"},
        "inventory_start_date": {
          "type":   "date",
          "format": "yyyy-MM-dd"
        },
        "inventory_end_date": {
          "type":   "date",
          "format": "yyyy-MM-dd"
        }
       }
    }
  }
}

这是我的数据列表:

POST _bulk
{ "index" : { "_index" : "data", "_type" : "_doc" } }
{ "product_code" : "20001", "color_code" : "001", "warehouse_id" : 5, "stock" : 10,"inventory_start_date" : "2019-01-01","inventory_end_date" : "2019-01-04"}
{ "index" : { "_index" : "data", "_type" : "_doc" } }
{ "product_code" : "20001", "color_code" : "001", "warehouse_id" : 5, "stock" : 4, "inventory_start_date" : "2019-01-04","inventory_end_date" : "2019-01-07"}
{ "index" : { "_index" : "data", "_type" : "_doc" } }
{ "product_code" : "20001", "color_code" : "001", "warehouse_id" : 5, "stock" : 0, "inventory_start_date" : "2019-01-07","inventory_end_date" : "2019-01-07"}

库存开始日期和库存结束日期将库存量保持在2个日期之间。

问题是:我该如何在2个日期范围之间获取数据。例如;在2019-01-05和2019-01-06之间获取文档。或者，在2019-01-01至2019-01-03之间获取文档。

考虑到您提到的文档，如果我想要带有 list 的文档列表，例如在2019-01-01和2019-01-04之间，然后我将查询扩展为如下，并在包含在range queries子句中的两个不同字段上使用bool must实现它。

inventory_start_date-在2019-01-01和2019-01-04之间

inventory_end_date-在2019-01-01和2019-01-04之间

询问

POST myindex/_search
{
  "query": {
    "bool": {
      "must": [
        {
          "range": {
            "inventory_start_date": {
              "gte": "2019-01-01",
              "lte": "2019-01-04"
            }
          }
        },
        {
          "range": {
            "inventory_end_date": {
              "gte": "2019-01-01",
              "lte": "2019-01-04"
            }
          }
        }
      ]
    }
  }
}

响应

{
  "took" : 1,
  "timed_out" : false,
  "_shards" : {
    "total" : 5,
    "successful" : 5,
    "skipped" : 0,
    "failed" : 0
  },
  "hits" : {
    "total" : 1,
    "max_score" : 2.0,
    "hits" : [
      {
        "_index" : "myindex",
        "_type" : "_doc",
        "_id" : "1",
        "_score" : 2.0,
        "_source" : {
          "product_code" : "20001",
          "color_code" : "001",
          "warehouse_id" : 5,
          "stock" : 10,
          "inventory_start_date" : "2019-01-01",
          "inventory_end_date" : "2019-01-04"
        }
      }
    ]
  }
}

同样，对于任何其他不同的日期范围，您都需要相应地构造查询。

让我知道是否有帮助。
