Question

我有一个在cmd中运行的mongo数据库。有一个名为usercollection的集合。还有一些我通过输入mongo shell得到的文件：

db.usercollection.find().sort({score: -1}).pretty()

输出：

{

}

问题在于我正在尝试将这些文档从分数最高的分类到分数最低的分类，并且输出完全是随机的（

我正在使用node.js在网站上显示这些文档，结果与控制台中的结果相同。

Answer 1

尝试：

db.usercollection.find().sort({score: 'desc'}).pretty()

mongodb后代按数字字段排序随机排序（node.js）
