Don’t forget to use Boolean search terms AND, NOT and OR for searches using more than one search term.
Ex. Sleep “and” Caffeine- gives you articles that contain the word Sleep and also contain the word Caffeine (most common way to use two or more search terms together)
Ex. Sleep “not” Caffeine- gives you articles that contain the word Sleep but NOT the word Caffeine
(a good way to limit your search)
Ex. Sleep “or” Caffeine- gives you articles that contain either the word Sleep or the word Caffeine or both Sleep and Caffeine in the same article. (this will give you the most results)
