Perhaps you should try some spelling variations:
presented » presente, presenta, presenteed, presentaed
presentan » presenta, presente, presentacion, presentean, presentaan
presenteada » presentada, presentado, presentadas, presenteeada, presentaeada
presenteaera » presentara, presentera, presentada, presenteeaera, presentaeaera
presentar » presenta, presentarse, presente, presentear, presentaar
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: ((estado OR presented) OR (((presentan OR presenteada) OR (presenteaera OR presentar)) OR present))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((estado or presented) or (((presentan or presenteada) or (presenteaera OR presentar)) or present))~".
• Adding a wildcard symbol may retrieve word variants: ((estado or presented) or (((presentan or presenteada) or (presenteaera OR presentar)) or present))*.
