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

Answer 1

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 。
