A more human search engine.

When you do a Google search, search terms entered are checked against all the documents stored on the Google servers, ranking the best at the top of the pile. Wolfram Alpha takes it a step further. Instead of just checking the words, the new pretender takes into account human language, looking at the question posed to find the best search, not just a string of words. It's called natural language processing and according to creator Stephen Wolfram, it takes web searching a considerable step forward. One expert describes the engine as a 'vast electronic brain'. We really hope that's reality, not just a figure of speech.
