mongodb 如何使用ne筛选多个不等数据？

数据： { "_id" : 1, "item" : "abc1", description: "product 1", qty: 300 } { "_id" : 2, "item" : "abc2", description: "product 2", qty: 200 } { "_id" : 3, "item" : "xyz1", description: "product 3", qty: 260 } { "_id" : 4, "item" : "VWZ1", description: "product 4", qty: 330 } { "_id" : 5, "item" : "VWZ2", description: "product 5", qty: 180 }

如何查询出qty不等于180和200的数据？
