我有像
这样的数组`var brand_arr = [ 'Acer', 'Asus', 'Dell', 'lenovo' ];
var cpuSpeed = [ '1.5', '2.0', '2.5', '3.0' ];`
我想对我的集合应用过滤，检索我的集合中包含 Brand_arr 数组中数据的任何值的所有文档，然后与 cpuSpeed 数组的任何值进行匹配。
brand_arr 的数据包含文档的品牌键值，cpuSpeed 数组中的数据包含处理器下的速度值。
最佳答案
使用$in :
product.find({brand: {$in: brand_arr}})
关于node.js - 如何根据数组中的数据过滤我的集合？，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/49600975/
