【问题描述】：
我是 MongoDB 的新手，我正在尝试进行如下典型搜索。
查询问题：必须显示不提供特定菜系的餐厅列表，并且他们的分数应该> 70并且餐厅纬度小于-65。

除了纬度小于-65之外，我几乎接近解决方案。请在下面找到我的查询。
db.addresses.find( { $and: [{"cuisine": { $not: /^A.*/ }}, {"grades.score":{ $gt: 70}}, {"address.coord":{ $lt: -65 } } ] } )
当我尝试以下查询时，它既没有抛出错误，也没有给出解决方案。
db.addresses.find( { $and: [{"cuisine": { $not: /^A.*/ }}, {"grades.score":{ $gt: 70}}, {"address.coord.1":{ $lt: -65 } } ] } )
请让我知道我在哪里犯了错误并纠正我。
谢谢
