Searching the World Wide Web is usually done using search engines. All search engines retrieve information, but each has unique features. Search methods and search results vary depending on what type of search engine you are using. The three main types of search engines are metasearch engines, directory search engines, and keyword search engines. For best results, read the search tips provided by each search engine.
