1. Definition of 'boolean' as commonly used in English

Boolean Logic, or Boolean Algebra -- A system of mathematical logic developed in the mid-19th century by the English mathematician George Boole (1815-64).

Boolean Searching -- The boolean algebra or boolean logic (originally developed by George Boole), boolean search, has been widely adopted for use in describing the simple logical operators (AND, OR, NOT) of Internet search engines .

The word 'boolean' does not appear in Webster's 1828 Dictionary, because Boole had not written his Investigation of the Laws of Thought until 1854. The term 'boolean' does not appear in any English dictionary until many years after Boole's death.
