Perhaps you should try some spelling variations:
prestamos » prestados, presentamos, estamos
presentando » presentada, presentacion, presentation, presentado, presentedo, presentaciondo, presenteando, presentaando
presentado » presenta, presented, presentar, presenteado, presentaado
presentaron » presentacion, presentation, presentarse, presentearon, presentaaron
presentan » presenta, presente, presentacion, presentean, presentaan
present » presente, presenta

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

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