Perhaps you should try some spelling variations:
presentados » presentado, presentadas, presentando, presenteados, presentaados
presentada » presentado, presenta, presentan, presenteada, presentaada
presentaron » presentation, presentan, presentarse, presentearon, presentaaron
presentae » presentare, presentase, presente, presenteae, presentaae
presentacion » presenteacion, presentaacion
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: (presentacion OR (((presentados OR presentada) OR presentaron) OR (presentae OR present)))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(presentacion or (((presentados OR presentada) or presentaron) or (presentae or present)))~".
• Adding a wildcard symbol may retrieve word variants: (presentacion or (((presentados OR presentada) or presentaron) or (presentae or present)))*.
