Perhaps you should try some spelling variations:
presentada » presented, presenteda, presenteada
presentar » presentarse, presente, presented, presenter, presentear
presentan » presente, presentacion, presenten, presentean
presentado » presented, presentacion, presentation, presentedo, presenteado
presenta » presente, presentea
presentea » presentera, presente, presented, presenteea
present » 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: ((presentada OR presentar) OR (((presentan OR presentado) OR (presenta OR presentea)) OR present))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((presentada OR presentar) or (((presentan or presentado) or (presenta or presentea)) or present))~".
• Adding a wildcard symbol may retrieve word variants: ((presentada OR presentar) or (((presentan or presentado) or (presenta or presentea)) or present))*.
