Perhaps you should try some spelling variations:
prestamo » prestamos, prestado, prestados
presentado » presenta, presentar, presentacion, presenteado, presentaado
presentan » presenta, presente, presentacion, presentean, presentaan
presenteaaan » presentaban, presentaran, presentaron, presenteeaaan, presentaeaaan
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 presenteaaan) OR (presented OR present)))~.
• Adding a wildcard symbol may retrieve word variants: (prestamo or (((presentado or presentan) or presenteaaan) or (presented or present)))*.
