YAHOO launches search of "Deep web"

Yahoo began testing a service yesterday that allows people to perform simultaneous searches for information contained within subscription-based Web sites. While most search engines crawl the Web and troll freely accessible sites, they cannot get into much of the so-called deep Web, vast amounts of data stored within paid and password-protected sites. Yahoo Search Subscriptions will allow search access to seven different subscription Web sites simultaneously, including the Financial Times and The Wall Street Journal Online.
