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