Perhaps you should try some spelling variations:
presented » presente, presentan, presenteed
presentaan » presentaban, presentaran, presentan, presenteaan, presentean
presentadas » presentada, presentado, presenteadas, presentedas
presentaea » presentada, presentara, presentaba, presenteaea, presenteea
present » presente
presenta » presentea, 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: (presented OR (((presentaan OR presentadas) OR presentaea) OR (present OR presenta)))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(presented or (((presentaan or presentadas) or presentaea) or (present OR presenta)))~".
• Adding a wildcard symbol may retrieve word variants: (presented or (((presentaan or presentadas) or presentaea) or (present OR presenta)))*.
