text: is it possible to search those site who are not submitted/registered on any search engine in world?   search engines follow all links on a website. if the site has links to it from another website, it will eventually be found and show up in a search. if it has no links from another site and is not submitted to a search engine for crawling it will not be found. (although there is a theory that some search engines crawl all registered domain names- this is not proven.)
