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