How to search for information

1. We use the quotation mark (") to put two words (ex. polar bear) together => "polar bear"
2. Do not use keywords (ex. the, an, a...) 
3. Use the correct search engine while you're searching (Yahoo, Google, Bing, Ask.com,...)
4. You can't use And, Or, Not in your search.
5. When you're searching, the least result is the better.
