Perhaps you should try some spelling variations:
presentados » presentado, presentadas, presentaron, presenteados, presentaados
presentaan » presentaban, presentan, presentaun, presenteaan, presentaaan
presentaran » presentaron, presentaban, presentara, presentearan, presentaaran
present » presente, presenta
presentaea » presenteaea, presentaaea, presentada, presentara, presentata
presentaba » presenteaba, presentaaba, presentaban, presentada, presentara

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: (estamos OR ((presentados OR (presentaan OR presentaran)) OR (present OR (presentaea OR presentaba))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(estamos or ((presentados or (presentaan OR presentaran)) or (present or (presentaea or presentaba))))~".
• Adding a wildcard symbol may retrieve word variants: (estamos or ((presentados or (presentaan OR presentaran)) or (present or (presentaea or presentaba))))*.
