How can I create a query that lists all work items when Date 1 is exceeded by Date 2?

I am trying to create a query that returns all work items where the due date is greater than the replan date. In this case, the due date is just sometime in the future and so is the replan date.  So I need a query that says:

Current user and due date>replan date.  When I choose due date or replan date in the query builder, it is only making a decision on the date, I need a relative comparison between the two dates.

any thoughts on this would be helpful
