Boolian Searches

A Boolian search will get you much more specific information.

Boolean expressions include words like OR, AND, AND NOT, and NEAR used to create relationships among the keywords in your search query. Parentheses ( ) can also be used in the Boolean query box to group expressions similar to the way you would group mathematical functions. Below is a list of expressions with their corresponding symbol (you may use either) and function.






Finds documents containing all of the specified words or phrases. peanut AND butter finds documents with both the word peanut and the word butter.



Finds documents containing at least one of the specified words or phrases. Peanut OR butter finds documents containing either peanut or butter. The found documents could contain both items, but not necessarily.



Excludes documents containing the specified word or phrase. Peanut AND NOT butter finds documents with peanut but not containing butter. NOT must be used with another operator, like AND. AltaVista does not accept 'peanut NOT butter'; instead, specify peanut AND NOTbutter..



Finds documents containing both specified words or phrases within 10 words of each other. peanut NEAR butter would find documents with peanut butter, but probably not any other kind of butter.

() Use parentheses to group complex Boolean phrases. For example, (peanut AND butter) AND (jelly or jam) finds documents with the words 'peanut butter and jelly' or 'peanut butter and jam' or both.
