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