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