Making the IP anonymous is one thing, but I suppose they're still keeping hold of the search query information? That can have privacy implications as well. The article could do with being more specific about what they actually do hang on to after the dates these search engines say they will get rid of info. Some queries can be pretty revealing, with or without an IP.
