It seems like there is no more room for new players on the market and yet new approaches to online searching are not stopping. One of new and interesting projects is - DeepDyve. This search engine is capable of finding up to 99% of all web-pages which are not found by other search engines. These pages are not linked to any other pages and that's why they're not indexed by many other search engines like Google.
In the present time DeepDyve already indexed 500 million pages. At the moment using the search engine you may find articles related to medicine, pharmacy, patent and life science only! In the future DeepDyve will be enhanced so users may find information regarding IT, science and energy.
