Perhaps you should try some spelling variations:
prestamo » prestamos, prestado, prestados
presentado » presenta, presentar, presentacion, presenteado, presentaado
presentan » presenta, presente, presentacion, presentean, presentaan
presentaaan » presentaban, presentaran, presentarian, presenteaaan, presentaaaan
presented » presente, presenta, presenteed, presentaed
present » presente, presenta

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

• If you are trying to use Boolean operators, they must be ALL CAPS: (prestamo OR (((presentado OR presentan) OR presentaaan) OR (presented OR present)))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(prestamo or (((presentado OR presentan) or presentaaan) or (presented or present)))~".
• Adding a wildcard symbol may retrieve word variants: (prestamo or (((presentado OR presentan) or presentaaan) or (presented or present)))*.
