如何做一个“不输入”查询在Mongo？ [英] How do I do a "NOT IN" query in Mongo?

问题描述

这是我的文档：

{ 
    title:"Happy thanksgiving",
    body: "come over for dinner",
    blocked:[
       {user:333, name:'john'},
       {user:994, name:'jessica'},
       {user:11, name: 'matt'},
    ]
}

>

What is the query to find all documents that do not have user 11 in "blocked"?

推荐答案

您可以使用

You can use $in or $nin for "not in"

示例...

> db.people.find({ crowd : { $nin: ["cool"] }});
