Google filtered terms the Chinese government required (by law), but did so by returning results saying that some items were filtered out specifically so users would know their results were filtered. Google never gave any information on who searched specific terms, but after some attacks on their servers in an apparent attempt to get this information, Google announced they would no longer filter searches for China. Talks on how to accomplish this broke down, and Google redirected their China site to Hong Kong, which has no censorship restrictions, but the Great Firewall seems to be filtering results.
