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