node.js - 如何使用mongoose(express.js)编写选择数据的条件？

例如，我给了5个移动卖家列表对象。我只想选择谁都在销售品牌：诺基亚，型号名称：Lumia，子模型：Lumia 735 TS，Lumia 510如何在快递中写条件，如果用户选择品牌：诺基亚，型号名称：Lumia，子型号：Lumia 735 TS我该如何在快递中写出条件，我已经给我的控制器请帮了我三天的苦苦挣扎。
在mongodb中存储的卖方列表

条件1：
 我想过滤仅销售商品的数据

品牌：诺基亚

型号：Lumia

子型号：Lumia 735 TS，Lumia 510

如果符合上述条件，则应显示这3个卖家

1，Poorvika手机

2.移动角落

3.流动市场

这3家店铺只卖

品牌：诺基亚

型号：Lumia

子型号：Lumia 735 TS，Lumia 510

条件2：

最佳答案

尝试

find({
    'Categories.brandname':'Nokia',
    'Categories.models.name':'Lumia',
    'Categories.models.submodel.name':
        {'$all':['Lumia 510', 'Lumia 735 TS']}
})

$all将为您提供同时出售Lumia 510和Lumia 735的商店。如果您需要选择这些模型之一的查询，请改用$in。
