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