Google sends out robots to archive every website it finds. These websites will be presented in the next update of the Google index. Several days before the updated database is available on www.google.com, you can get a preview of the new data index on www2.google.com and www3.google.com. The search results vary during these updates allowing you to "see into the future" of where your site will be listed in the results before the main database is updated.
