Here's the official announcement on the launch of Google's How Search Works
Today we're releasing a similar website called How Search Works.
Here you can follow the entire life of a search query, from the web, to crawling and indexing, to algorithmic ranking and serving, to fighting webspam. The site complements existing resources, including this blog, the help center, user forums, Webmaster Tools, and in-depth research papers.
A few things you'll find:
An interactive, graphical explanation of Google Search
A view into major search algorithms and features
A 43-page document explaining how we evaluate our results
A live slideshow of spam as we remove it
Graphs illustrating the spam problem and how we fight it
