Search Hints

The system will try to find similar spellings or plurals automatically. If you are unsure of a spelling try using the ~ symbol at the end of a single word term.

  • Use AND, OR, or NOT for combining terms (operators must be ALL CAPS). By default your search terms will automatically be combined using "AND". For example
    • heart AND surgery
    • food OR nutrition
    • cancer NOT chemotherapy
  • Enclose a phrase in quotation marks to search for that exact phrase.
    For example: "abdominal pain"
  • Use * to stem or truncate a word, or as a wildcard in the middle of a word
    For example: diabet*
  • + - && || ! ( ) { } [ ] ^ " ~ * : ? each have a special meaning when used in a search. If you wish to use them according to their standard grammatical usage you must escape each with a backwards slash.
    For example: Diabetes\: What do the Numbers Mean\?
