The authors have confirmed that when a google.fr or google.de search yields results that have been excluded (relative to the full results available on the ordinary google.com site), the French and german versions of Google simply omit the results at issue. The screenshot below (prepared on October 21, 2002) shows a search for the word "stormfront" on google.com (left window) versus the same search on google.de (right window). Notice that the first three results on the google.com search are stormfront.org, while the google.de search omits these results, then continues with the sites ranked lower by google.com.
Interested readers can compare these searches for themselves, using their own computers, web browsers, and Internet connections. See the google.com and google.de 'stormfront' searches in a popup, or compare them in ordinary windows: a search for Stormfront on google.com versus the same search on google.de.
