如何在mongoose中查询数组[对象]结构？

Question

我有数组[object] schema：

var operation = new Schema({
    name:{type:String},
    number:[Number],
});

var Info = new Schema({
    operation:[operation],
}); 

当operation.name =＆＃39; jack＆＃39;;

如何通过Info Schema查询条件？

 Info.findOne({
    condition
 },function(e,r){

 });
