The code Below returns above result:下面的代码返回上面的结果：
var stockAccount = await Stock.aggregate([
{
$match: {
userEmail: req.body.userEmail,
},
},
{
$match: {
"transactions.date": {
$gte: req.body.fromDate,
$lte: req.body.toDate,
},
},
},
]);
I need to filter the "transactions" array based on date.我需要根据日期过滤“交易”数组。 For example: From "09/05/2020" to "23/05/2020".例如：从“09/05/2020”到“23/05/2020”。 Expected Output:预期 Output：

Is there an query to achieve this?是否有查询来实现这一点？ Thank you.谢谢你。

I believe aggregation is not needed in your case.我相信您的情况不需要聚合。
var stockAccount = await Stock.find({
userEmail: req.body.userEmail,
"transactions.date": {
$gte: req.body.fromDate,
$lte: req.body.toDate,
}
});
Note: It seems like the format of the date in the database is a string.注意：数据库中日期的格式似乎是一个字符串。 So, date comparison should not work.因此，日期比较不应该起作用。
