Yahoo!'s rolled out a brand new search engine. It has its own index
and ranking mechanisms, casting aside its long-standing use of Google-powered
It sets in
motion a new 3-way race between Google, Yahoo! and MSN for the claim
of search engine champion.
Ever since Yahoo's acquisition of Inktomi nearly a year ago, speculation
focused on when the company would replace its Google powered search
results with results from Inktomi's index.
Yahoo hasn't replaced Google with Inktomi. Instead, the company
developed a brand-new search engine.
Yahoo waited until now to switch
from Google to be certain users would have the best experience
possible after the transition.
The new search engine is for web results only. Image search
remains powered by Google. News search is still a combination of
Yahoo's own editorial and technological resources.
presentation is still very similar to Google. There's
copy of each indexed page -- now served from Yahoo, not Google. Just
about everything else on search result pages looks the same.
The Yahoo Search index captures the full text of Web pages, up to
a 500K limit.
Yahoo won't tell us how big its index is, despite Google's
recent announcement it has expanded its index to nearly 4.3 billion

Last year, before Yahoo acquired Overture, Overture was busy acquiring
AltaVista and AlltheWeb. Speculation was Overture would kill off
AltaVista's technology and power both search sites with AlltheWeb's
To the contrary, both search engines maintain their independent
indexes. In July 2003, Yahoo bought Overture.
Both AltaVista and
AlltheWeb continue to maintain separate indexes. Yahoo isn't saying
publicly whether this will change with the introduction of the new
Yahoo Search Technology index.
