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