Perhaps you should try some spelling variations:
presentado » presenta, presented, presentar, presenteado, presentaado
presentaban » presentaron, presentada, presentadas, presenteaban, presentaaban
presentaran » presentaron, presentara, presentarse, presentearan, presentaaran
presentan » presenta, presente, presentacion, presentean, presentaan
presentedecada » presenteedecada, presentaedecada
present » presente, presenta

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (presentado or (((presentaban or (presentaran OR presentan)) or presentedecada) or present))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (presentado OR (((presentaban OR (presentaran OR presentan)) OR presentedecada) OR present))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(presentado or (((presentaban or (presentaran OR presentan)) or presentedecada) or present))*".
