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