A search engine is used to store info and make it available for search results. The very first search engine was Wandex. The predecessor to today’s search engines was WebCrawler. Around 2001 Google became thee search engine. Google pioneered page rank and link popularity. The google search page is not fancy, but it does the job and that seems to be what people want. The other biggie in the world is Yahoo. The newest to hit the scene is msn search.
