【问题描述】：
我正在尝试使用 MongoDB 和 GoLang 根据某些过滤器值获取记录，但它返回空数据。我在下面解释我的 json 记录。

这是我的 mongoDB json 格式。我在下面解释我的代码。
func SalesOrderSearch(SalesOrder *models.OrderFilterData) map[string]interface{} {
logger.Log.Println("OrderRepository SalesOrderSearch Function Begin")
session, error := driver.Connect()
db := session.DB(config.Configuration.Database)
var resp map[string]interface{}
Status := SalesOrder.Status
AdmissionID := SalesOrder.AdmissionID
Grade := SalesOrder.Grade
ProductName := SalesOrder.ProductName
Category := SalesOrder.Category
Branch := SalesOrder.Branch
Vendor := SalesOrder.Vendor
fmt.Println(AdmissionID,Grade,ProductName,Branch,Category,Vendor)
resourceManager := resources.ResourceManager{}
if error != nil {
resp := utils.Message(resourceManager.GetProperty(constants.ERROR), resourceManager.GetProperty(constants.DB_SERVER_NOT_REACHABLE_CODE), resourceManager.GetProperty(constants.DB_SERVER_NOT_REACHABLE_DESC))
return resp
} else {
var result []interface{}
filter := []bson.M{
bson.M{"$match": bson.M{"OrderStatus": Status, "Customer": bson.M{"$elemMatch":bson.M{"Children":bson.M{"$elemMatch":bson.M{"StudentAdmissionID":AdmissionID}}}},"Products":bson.M{"$elemMatch":bson.M{"ProductName":ProductName,"CategoryName":Category }}}},
bson.M{ "$skip" : 0 },
bson.M{ "$limit" : 5 },
}
err := db.C(ORDERCOLLECTION).Pipe(filter).All(&result)
fmt.Println(err);
if err != nil {
resp = utils.Message(resourceManager.GetProperty(constants.ERROR), resourceManager.GetProperty(constants.CUSTOMER_SEARCH_NOTFOUND_CODE), resourceManager.GetProperty(constants.CUSTOMER_SEARCH_NOTFOUND_DESC))
} else {
resp = utils.Message(resourceManager.GetProperty(constants.SUCCESS), resourceManager.GetProperty(constants.CUSTOMER_SEARCH_FOUND_CODE), resourceManager.GetProperty(constants.CUSTOMER_SEARCH_FOUND_DESC))
resp["data"] = result
}
}
defer session.Close()
return resp
}
这里我需要根据给定的某些过滤条件搜索记录，并且它应该是 or 条件意味着如果所有值都在那里，那么它将根据所有值匹配记录，或者如果一些值在那里它也将匹配相应的记录。但就我而言，它根本没有获取记录。谁能帮我解决这个问题。
