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