  1. Boolean Searches • Named for British mathematician George Boole • System of logic designed to produce much better search results • Bartenders use Boolean logic every day to fill customers’ mixed drink orders

  2. Remember the Search “Mixers!” • Bartenders combine alcohol to make drinks. • Operators combinekeywords to make search strings. Vodka AND Roses Lime Juice Vodka AND Kahlua = Vodka Gimlet AND milk = White Russian

  3. Research is likeadding mixers • Too many choices using the subject History • 405,393 articles in ProQuest Research Library • Decide on your main ingredient (History), then blend it with mixers (place, time period, person, event) History AND England AND Tudor AND Elizabeth History ANDJapan AND Tokugawa AND Shogunate

  4. AND • Narrows your search • Retrieves only documents that contain all your keywords • The more keywords, the fewer the results • Gin and Rum and Tequila and Vodka and “sour mix” and Cola • “Medical research” and ethics and “stem cells” • “Central Park” and Christo and art

  5. OR • Expands the search • Retrieves documents in which either or both keywords appear • The more keywords, the greater the results • Also use for synonyms • Stolichnaya or Smirnoff or Finlandia or Absolut or Chopin or Belvedere or “Grey Goose” or VanGogh • Vodka and (Midori or “peach schnapps” or “blue curacao” or “apple pucker”) • college or university • feminism or “women’s rights”

  6. NOT • Narrows the search • Retrieves documents in which only the first keyword appears • Cosmopolitan NOT splash of cranberry juice • Cowboys NOT Football • Beware! The computer will not retrieve documents where both keywords appear. • Fuzzy Navel NOT peach schnapps • vegetarianism NOT “animal rights”

  7. QUOTATION MARKS • Not all databases or search engines allow this option • Words inside quotation marks become a phrase. • Computer searches for the words in that exact order. • Like the layered shot Chocolate Covered Cherry • “green tea” • “Wonder Woman”

  8. NESTING • Combines several search statements into one search • Parentheses separate keywords when you are using more than 1 operator and 3 or more keywords • Think about math… (8-4) * (12-6) = 24, but the answer would be different without the parentheses • (Jose Cuervo or Sauza) AND (Gran Marnier or Cointreau or Triple Sec) AND (lemon or lime) NOT Salt • (MDMA or ecstasy) AND (physiological or medical) AND effects

  9. TRUNCATION • Use * or # at end of word. • Computer retrieves documents containing variations of a root word. • Sloe Gin Fizz: After Midnight, Against the Wall, Mexican Style, A Little Bit of English, With a Kiss • environment* [Finds: environment, environmental, environmentalism, etc.] • Use ? inside a word • Computer retrieves various spellings of a word • Wom?n [Finds: woman, women, womin, womyn]
