"For the last several months, a large team of Googlers has been working on a secret project: a next-generation architecture for Google's web search. It's the first step in a process that will let us push the envelope on size, indexing speed, accuracy, comprehensiveness and other dimensions," two Google engineers write on the development blog.
It is inviting people to test-drive the engine and provide feedback on the results. To do so requires comparing results here on the new version and there on the existing version in crawling, indexing and ranking.
The implications are significant in Google's efforts to continue to pave the way in linking content to advertising.
