Perhaps you should try some spelling variations:
presentada » presentado, presenta, presented, presenteada, presentaada
presentan » presenta, presente, presentacion, presentean, presentaan
presentados » presentado, presentadas, presentaron, presenteados, presentaados
presentaba » presentaban, presentadas, presentaran, presenteaba, presentaaba
presentara » presentar, presentarse, presentaron, presenteara, presentaara
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: (presentada OR (((presentan OR presentados) OR (presentaba OR presentara)) OR present))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(presentada or (((presentan or presentados) or (presentaba OR presentara)) or present))~".
• Adding a wildcard symbol may retrieve word variants: (presentada or (((presentan or presentados) or (presentaba OR presentara)) or present))*.
