• Performing a fuzzy search may retrieve terms with similar spellings: (("international waters") or ((((("international patient") or ((("international water") OR ("international actor"))))) or ("international student"))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("international waters") OR ((((("international patient") OR ((("international water") OR ("international actor"))))) OR ("international student")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"international waters\") or (((((\"international patient\") or (((\"international water\") OR (\"international actor\"))))) or (\"international student\"))))".
• Removing quotes may allow a broader search: (( international waters ) or ((((( international patient ) or ((( international water ) OR ( international actor ))))) or ( international student )))).
• Adding a wildcard symbol may retrieve word variants: (("international waters") or ((((("international patient") or ((("international water") OR ("international actor"))))) or ("international student"))))*.
