Strange Search results, using

I have been finding that many of the search engines like Google, Yahoo, Technorati, and Feedster are returning different search results for the words . Now I don’t use these words in real text on this post as an example of this. Now I know that certain words have been blocked on Google. And most of these are for the Chinese government. But the odd results are showing up in Europe as well. are important words that should not be blocked.
