An undocumented but powerful feature of Google's search is the ability to search within a particular date range. Before delving into the actual use of date range searching, there are a few things you should know. First, a date range search has nothing to do with the creation date of the content and everything to do with the indexing date of the content. If I create a page on March 8, 1999, for instance, and Google doesn't get around to indexing it until May 22, 2002, for the purposes of a date range search, the date in question is May 22, 2002.
