Site:www.example.com Returns 5x Greater Number of Pages Than on the Site

A webmasterworld poster reports he is seeing more than 5x of pages showing in the site: command of google, as many are aware of site: command shows the pages that are indexed under a particular domain, It is an useful command for various reason one good is reason is if you want to find a particular information on a news site or some information site we can use the keyword that document contains with the site:www.domain.com and find that page,



From what i can see there are no changes in site: command, probably what that user found was just a glitch,
