我正在寻找一个查询，该查询只能返回主文档数组内的某些文档。下面是存储在数据库中的集合：

下面的代码返回以上结果：
var stockAccount = await Stock.aggregate([
{
$match: {
userEmail: req.body.userEmail,
},
},
{
$match: {
"transactions.date": {
$gte: req.body.fromDate,
$lte: req.body.toDate,
},
},
},
]);
我需要根据日期过滤“交易”数组。例如：从“ 09/05/2020”到“ 23/05/2020”。预期输出：

是否有查询来实现？谢谢。
答案 0 :(得分：0)
我认为您的情况不需要汇总。
var stockAccount = await Stock.find({
userEmail: req.body.userEmail,
"transactions.date": {
$gte: req.body.fromDate,
$lte: req.body.toDate,
}
});
注意：数据库中日期的格式似乎是字符串。因此，日期比较不起作用。
