I found the article, How a Search Engine Works, interesting. I had no idea how steps it take to formality a search. A Google search takes only seconds. Now, Google search engine is kind of a mind reader. For example, if I want to search for ear ache, by time I am done typing ear, Google already provided me with a drop list of the most common search for ear. On the list there is, ear ache, ear dysfunction, or ear infection.  How can a process, which is broken down into four segments, then each segments has steps, be done so quickly?
