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