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