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