Tips

  1. To search for an exact word or phrase use quotes (" ") around your search phrase. Example: "screening for diabetic retinopathy"
  2. To exclude a word from your search add a dash (-) before the word in your search phrase. Example: education -children
  3. To include similar words add a tilde sign (~) immediately in front of your search word. Example: ~food facts includes results for “nutrition facts”
  4. Use an asterisk (*) within your search phrase for any unknown words in your search. Example: “a * saved is a * earned”
  5. To search for pages that include one of several words, include OR (capitalized) between your search words. Example: Incidence OR Prevalance
