Yahoo's index is bigger than Google's

Yahoo proudly unveiled today its search engine has indexed more than 20.8 billion Web documents and images, nearly double the material indexed by Google. The search engine claims it now indexes 19.2 billion documents and 1.6 billion images, while Google only tracks 11.3 billion objects, including 8.2 billion webpages and 2.1 billion images.

In a statement late Monday, Google spokesman Nate Tyler questioned whether the size of Yahoo's search index had really surpassed its own. "We welcome innovation in search, but as of this afternoon we have not been able to verify a substantial increase to Yahoo's web index via their search results," Tyler said.

However, it is not really the quantity but the quality of search engine pages that really matters. More details at Yahoo News
