There are over 1000 search engines on the internet, although Google is the one used by the majority of people. While Google is still the best search engine for locating information, it’s not the best at presenting the results.
Synonym Search (“~”) immediately in front of your search term. • Word definition (define: ) • Google alerts http://www.google.com/alerts are email updates of the latest relevant Google results based on your choice of query or topic. • Google reader http://www.google.com/reader constantly checks your favourite news sites and blogs for new content and posts them to one easy page. • Google Custom Search Engine or Google Coop http://www.google.com/coop/cse can be used to create a search engine that includes a Web site or a collection of Web sites.
