Boolean Operators

Boolean Operators

AND
	This operator tells the computer to look for both words and the result MUST contain both words. For example; Weather AND Tornadoes. This search says that any results must contain both the word "weather" and the word "tornadoes".
OR
	This operator tells the computer to look for either one of the words that you want to find. For example; Weather OR Tornadoes. This search tells the computer to look for either the word "weather" or the word "tornadoes" and will bring up those results. Something that has the word "weather" in it does not necessarily have to have the word "tornadoes" and vice versa.
NOT
	This operator tells the computer to exclude something from your search. If you were doing a search for weather information, and wanted to exclude anything about blizzards, you would type your search to say, weather NOT blizzards.
Truncation
	Truncation is used when you want to find all forms of a particular word. This is especially useful when you want to include plurals. For example; if you wanted to find information on beauty. There are several endings to this word such as; beautify, beautification, beautifully, and beautiful, just to name a few. When you search, you want to be able to pull all of these up without having to remember all the forms and typing them in. To do this, you will use truncation to search for it. You would type it in like this: beaut*. The asterisk symbol tells the computer to look for a particular string of letters or numbers, and anything could follow the asterisk.
