I frequently find myself trying to check ranges looking for edits and sleeper account creations by vandals and banned users on highly dynamic ISPs (or who forcibly reset their connection frequently). If there are more than 5000 edits in the database, the system returns an error message with a partial list of IPs, and it is necessary to try progressively smaller ranges (and more of them) to do a complete search.  However, I usually don't need to see all the edits from the checkuser table, the edits from the last 5 or 10 days are usually sufficient to find recent sleepers or other activity.  I propose that when a range check returns the "exceeds 5000 edits" error message, the system should ask, "would you like to limit your search to the last X days and recheck?" where X could be a dropdown box (say, 1, 3, 5, 10 and 30 days) or free-form entry.
