Perhaps you should try some spelling variations:
prestamos » prestados, presentamos, estamos
presentados » presentado, presentadas, presentada, presentedos, presenteados
presentaron » presentacion, presentation, presentan, presenteron, presentearon
presented » presente, presentan, presenteed
presenta » presente, presentea
presenteeea » presentee, presentees, presentesen, presenteeeea
present » 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 (presentados OR presentaron)) OR ((presented OR (presenta OR presenteeea)) OR present))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((prestamos or (presentados OR presentaron)) or ((presented or (presenta or presenteeea)) or present))~".
• Adding a wildcard symbol may retrieve word variants: ((prestamos or (presentados OR presentaron)) or ((presented or (presenta or presenteeea)) or present))*.
