我查询出来的结果如下

"docs": [
        {
            "_id": "5a1cb71f52d3ca6a96a18aa2",
            "list": 1,
        },
        {
            "_id": "5a1cba7b52d3ca6a96a18bb7",
            "list": 10
        },
        {
            "_id": "5a1cbb3052d3ca6a96a18bf0",
            "list": 11
        },
        {
            "_id": "5a1bb90152d3ca6a96a17de5",
            "list": 12
        }
    ],

我想让数据的list按照数字大小来排序，也就是list:1后面那条数据要接list:2。而不是字典排序。
