I don't want to be negative but you guys have to actually know what the engine does. First off, it's "WolframAlpha" not wolphram. It is named after Stephen Wolfram who is the head/creator of Wolfram research. It is constantly being updated and acts as a "knowledge" engine. You're not supposed to enter long search queries. There is a big video tutorial on the homepage. It is based off the Mathematica system which has been in development for 23 years. It constantly gathers data from all over the web and has an ever expanding database of answers.
