A bit of history!
Boolean operators are named for George Boole (1815-1864), an English Mathematician and Philosopher. Boolean Algebra and Symbolic Logic both derive from his work. Boole is generally considered the father of modern computer science. Most electronic indexes (databases) require the use of Boolean operators in parsing search terms, although this is not always apparent. Boolean search statements are incredibly powerful in retrieving what you need provided 1) the statement is formatted correctly and 2) your choice of search terms is correct for the topic you are researching.
