Boolean

Boolean
   Any variable that can have a logical value of true or false. Named after George Boole, the developer of a branch of algebra based on the values of true and false, Boolean works with logical rather than numeric relationships.
   Boolean operators include AND (logical conjunction), OR (logical inclusion), XOR (exclusive or), and NOT (logical negation) and are sometimes described as logical operators.
   Many popular Internet search engines allow Boolean searches.
