Perhaps you should try some spelling variations:
prestamos » prestados, presentamos, estamos
presentedans » presentadas, presentedin, presented
presentan » presente, present, presentacion, presenten
presentaron » presentacion, presentation, presentarse, presenteron
presentado » presented, presentar, presentacion, presentedo
presenta » presente

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: (prestamos OR (((presentedans OR presentan) OR presentaron) OR (presentado OR presenta)))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(prestamos or (((presentedans OR presentan) or presentaron) or (presentado or presenta)))~".
• Adding a wildcard symbol may retrieve word variants: (prestamos or (((presentedans OR presentan) or presentaron) or (presentado or presenta)))*.
