Assignment 9: How search engines work?

How search engines work is not as simple as a lot of us thought it was. It’s a lot of work for those engineers to keep search engines such as Google, Yahoo!, Bing etc.. updated. Some searches are updated every minutes, like the news or sports or something. But when you search something more specific; for example news on a soccer team, the searches are updated not so often. As it was mentioned in the article, 20% of the searches done everyday haven’t been searched for like 3 months so there’s a tough job for the engineers. They have to guess what the people will search every other day and that’s not easy at all. However, I do believe that there must be like a pattern or something which will help them in guessing those searches.
