Question

我遇到了在elasticsearch上按日期排序的问题。根据elasticsearch http://www.elasticsearch.org/guide/en/elasticsearch/guide/current/_sorting.html

提供的文档

我使用以下代码按日期排序

{"sort":{"posted_on":{"order":"desc"}}}

以下是结果

{

    "total": 1,
    "successful": 1,
    "failed": 0

查询中有什么问题吗？谢谢， Aashish

Answer 1

回答这个问题，就像aashish说的那样。发生这种情况时，您可能需要查看您的地图字段，并确保该字段的类型＆＃34;日期＆＃34;。

您可能还想按照here

中的说明指定日期格式

按日期排序的elasticsearch不起作用
