I have a collection name ACCOUNT where ABC-PQR-123-56789 is a key field.
each filed separated by “-” have some meaning and all together they make a unique combination.
Once the account is closed the key field is appended with open account date.
like ABC-PQR-123-56789-23062022 (eg. if it got closed today)
But for some reason account is created again ABC-PQR-123-56789 and hence there are 2 account for same id
this should not happen and trying to find out how many such key id exist in my collection.
could you please help me to find such cases where one account is open and one closed with appended account open date.
