Google tries to be helpful and crawls all kinds of documents just to show direct answers when you type a query. The feature called Google Q&A uses artificial intelligence to automatically discover patterns in web documents.

Lately, you could see direct answers for much more queries. For example:

• flu symptoms -> Fever - May be high; Headache; Tiredness; Dry cough; Sore throat; Stuffy, congested nose
• Paris Hilton height -> 5' 7½" (1.71 M)
• California motto -> Eureka I Have Found It

But Google's AI technology is not perfect and, although they try to use more sources to make sure they're on the right track, this doesn't happen all the time. Google trusts a lot of obscure wikis and profile pages, who fail to provide meaningful information outside their limited scope.

• text file -> To escape
• file size -> Used for
• field name -> Name of file, no path. Must be unique within topic
• file user->The REMOTE USER, Not WikiName
• Victoria size-> Height: 5'6" (the answer is from an escort site; I was trying to find how big is Victoria, a state from Australia)
• Katie's education - High School (Katie is a user of the social network yub.com)
• Eric's favorite runs - Upper Yough, Upper Gauley, Sec IV Chat, Watuga (Eric is a user of a whitewater site)
