在这个json数据中我只会获取哪些是min_price：1。这里有些记录没有min_price它有面额所以我需要只有min_price查询mongodb。
提前感谢您的支持
答案 0 :(得分：0)
这将获取具有min_price : 1
db.collection.find({"brands.rewards.min_price" : 1})
如果您只想要价格为1的奖励
db.collection.aggregate([{"$unwind" : "$brands"},{"$unwind" : "$rewards"},{$match : {brands.rewards.min_price : 1}}])
如果它不满足您的要求，请将输出发布到您想要的内容
