How to add date filter in transactional event log api ?

Hi All,

I am trying to fetch logs for a given event and email id within the date range, but not getting the actual response?

For example : 

Method : GET

https://mc.adobe.io/<instance_name>/campaign/mc<test>/<eventname>/byEmail/processed?email=<emailid>&processed=<date(yyyy-mm-dd)>

If I pass only email id, then it's returning all emails sent to that person for the particular event.

https://mc.adobe.io/<instance_name>/campaign/mc<test>/<eventname>/byEmail?email=<emailid>

Is there anything wrong I am doing while passing the date as a parameter?

I didn't find any reference on how to pass the date range (from-date and to-date) as a parameter.

Thanks in advance
