=Boolean Logic= George Boole, English mathematician, developed Boolean Logic, also known as the "mathematics of logic", in the mid-19th century. Boolean Logic is the foundation of all electronic circuits in a computer and is used whenever searching on the Internet. It primarily consists of 3 functions: Most search engines allow you to use shortcuts, or implied Boolean operators, like the plus (+) sign for AND or the minus (-) sign for NOT. Some search engines require you to use their Advanced Search features to take full advantage of Boolean Logic.
 * 1) AND divides search words or phrases and is used to narrow a search (In most search engines, the + sign can be used in place of the word AND in all caps). For example: dog AND poodle will return "hits" for Web sites that contain both dog and poodle.
 * 2) OR combines search words or phrases to widen a search. For example: dog OR poodle will return "hits" for Web sites that contain either dog or poodle.
 * 3) NOT eliminates like words or phrases to narrow a search. For example: dog NOT poodle will return "hits" for Web sites that contain dog but not poodles. (In most search engines, the - sign can be used in place of the word NOT in all caps).
