yes but they would get a warrant to search the filing cabinet for the named documents. They *might* discover other interesting documents incidental to the search in the cabinet and they would be allowed access to those. They would not be allowed to remove or copy the other documents. They also would not be allowed to drive to your parents place 5 hours away and search thur boxes of old files there from 10 years ago, unless they specified doing so on the warrant and it would only be allowed if there was reason to think related documents could be there.
E-mailboxes are not perfectly analogous to physical filing containers. People tend to have all of there electronic documents in once place. I think the basic principle of limited searches though means if you can't restrict where, because there isn't an atomic concept of place, than you must restrict what. So I still say minimally having to name a reasonable date range is not asking to much of LEOs.
