複数検索クエリの50%に対して検索結果が表示できないとMSN。しかし75%のユーザは自分の疑問に対する回答を家族ではなくウェブに求めている。世界には500万テラバイトに相当する情報があるが、そのうちオンラインで利用可能なのは170テラバイトに過ぎないというのに。
MSN's own research found 50% of complex queries go unanswered, while even more simple searches take an average of 11 minutes. Despite this it found that there was real hunger for web-based answers. Three-quarters of people would rather use the web to answer their questions than their own family members. [" The future of search looks bright" BBC News, Friday, 3 June, 2005, 08:08 GMT 09:08 UK]
Jeff Levick, Vertical Markets Director of Google Europe pointed out that only a fraction of the world's information was currently online. According to estimates by scientists at the University of California, Berkeley, there is around five million terabytes of information in the world, of which just 170 terabytes is available online.
