我在 QBE 中寻找日期范围查询。我正在尝试以下查询示例

https://Server:port/v1/qbe?format=json&pageLength=10&start=1&directory=/json/&options=search_option_advanced_date&query={"$query":{
"$and":[{"creation_date":{"$le":"2018-12-12T05:40:47.496"}},{"creation_date":{"$ge":"2017-12-12T05:40:47.496"}}],"$filtered":true}}

在这里,我在“/Creation_Date_date”上创建了路径范围索引和“Creation_Date_date”上的元素范围索引也在持久选项的 search_option_advanced_date 文件的约束下添加

<constraint name="creation_date">
   <range type="xs:date">
     <element name="Creation_Date_date"/>
   </range>
 </constraint>

虽然结果应该被获取,但我得到了以下空白

{
  "snippet-format":"snippet", 
  "total":0, 
  "start":1, 
  "page-length": 10, 
  "selected": "include-with-ancestors", 
  "results":[], 
  "facets": {
    "EntityType":{"type":"xs:string", "facetValues":[]}, 
    "Category":{"type":"xs:string", "facetValues":[]}, 
    "Genre":{"type":"xs:string", "facetValues":[]}, 
    "creation_date":{"type":"xs:date", "facetValues":[]}
  }, 
  "metrics": {
    "query-resolution-time":"PT0.016599S", 
   "facet-resolution-time":"PT0.000578S", 
   "extract-resolution-time":null, "total-time":"PT0.017743S"
  }
}

要使用持久查询选项,QBE 查询必须使用约束属性来指定查询选项:

http://docs.marklogic.com/guide/search-dev/qbe#id_32338

也就是说,如果您使用查询选项,使用组合查询通常更直接:

http://docs.marklogic.com/guide/rest-dev/search#id_69918

最后,约束被键入为 xs:date 值,但查询提供 xs:dateTime 值。

希望有帮助,
