The Deep Web (also called the Deepnet , the Invisible Web , the Undernet or the hidden Web ) is World Wide Web content that is not part of the Surface Web , which is indexed by standard search engines .

Lors d'une navigation en Antarctique pour prélever des échantillons de glace sur des icebergs, si vous vous limitez à leur partie émergée, vous vous privez de la surface immergée, en moyenne 50 fois plus importante. Sur le web, c'est la même chose !
