Perhaps you should try some spelling variations:
prestamo » prestar, presta, prestan
prestamos » prestars, prestas, prestans, presentamos, estamos
prestado » presentado, prestadora, estado
prestados » presentados, prestadoras, estados, prestadores
presentaron » presentacion, presentan, presentarse
presentation » presentacion, presentan, presentado

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: ((prestamo or prestado) or ((prestamos OR prestados) or (presentaron or presentation)))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((prestamo OR prestado) OR ((prestamos OR prestados) OR (presentaron OR presentation))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((prestamo or prestado) or ((prestamos OR prestados) or (presentaron or presentation)))".
• Adding a wildcard symbol may retrieve word variants: ((prestamo or prestado) or ((prestamos OR prestados) or (presentaron or presentation)))*.
