Google, the world’s most popular search engine, has more tricks than a New York brothel. Some of these tricks are as follows:

• Search within a specific site – by searching “site:whateverSite.com keywords” (without the quotes), you can restrict Google’s searches to a specific site. For example, if I typed “site:jerrytravis.com patience” into Google, only jerrytravis.com would be searched for the keyword patience.
• Search for definitions – by searching “define:some word” into Google, you can gain access to dozens of dictionaries. This is especially helpful for specialized vocabularies, such as legal or medical, that may not appear in a standard dictionary.
• Do calculations and conversions – Google will now perform mathmatical calculations for you. If you type in “10 * 20” Google will tell you the answer is 200. Almost all mathmatical notation is recognized. Also, Google can now do conversions. For example, searching “1 ounce in liters” returns “1 US fluid ounce = 0.0295735297 liters” The conversion engine supports most metrics.
