Answer to Question 1

Boolean logic was developed by a 19th century English mathematician named George Boole, which allows an Internet searcher to use three primary commands that will help reduce and/or expand return results. The three standard Boolean search terms are: the plus symbol (e.g. police +officer) or the AND term (e.g. police AND officer), the minus symbol (e.g. police-officer) or the NOT term (e.g. police NOT officer), and the OR term (e.g. police OR officer).
