Q7. GPS: Recently, there was a lot of controversy whether Yahoo index size is bigger than Google (also here). How big is Yahoo index and how does it compare with Google?

Usama Fayyad: In August 2005, Yahoo! Search reached a significant milestone -- our index provides access to over 20 billion items. This includes just over 19.2 billion web documents, 1.6 billion images, and over 50 million audio and video files. This happened to be a much larger index than our competitors were boasting to have and for some reason they reacted very negatively to the facts. The facts are there, and I am sure we will see the competitors soon reverse position and start announcing a much larger index themselves. We continue to believe that comprehensiveness (measured by index size) is only one dimension of the quality of a search engine. There are many other relevant metrics for relevance of search result, and we are obsessively focused on them: quantitatively and qualitatively. Finally, we don't comment on the index size of our competitors.
