Google's Advanced Operator List has no entry for DATE, so I don't know how you could use
CPF's Google form to bring them up that way. On the other hand, if you go directly to the Google Advanced Search page and click on the link about half way down that says: "Date, usage rights, numeric range, and more," you'll get a page with more option fields. Under DATE you can chose to only return results from 24 hrs, 1 week, etc.
