Show tickets done by a specific user for the past 3 weeks

[Joao Borges]

How can I add a filter to show tickets marked as done for a specific user "JOHN" for the past 3 weeks /month.Where the user is the one responsible to close the tickets

So far i have the following

     project = BUSINESS AND status changed to closed BEFORE "2020/04/25" AFTER "2020/04/01 00:00" 

Thanks

If you can assume John is the assignee then maybe this...

project = BUSINESS AND assignee = “John” and status changed TO done after 2020-04-01

If you want a specific date range...

project = BUSINESS AND assignee = “John” and status changed TO done after 2020-03-01 and status changed to Done before 2020-04-01
