What are search engines and how do they work?
A search engine is quite simply a website that helps you search the web. From the surfer’s view, they have a search box and a click to make. But, behind the scenes, is an extremely complex piece of software that pattern matches your key phrase with its database and then sorts the results in order of rank. And, who decides all this? Well they are known as the "search engine corporations" – organisations such as Google, Yahoo and Ask Jeeves to name but a few.
