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