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