Perhaps you should try some spelling variations:
presentaban » presentaron, presentada, presentadas, presenteaban, presentaaban
presenten » presente, presented, presentes, presenteen, presentaen
presentaaan » presentaran, presentarian, presentaron, presenteaaan, presentaaaan
presentan » presenta, presente, presentacion, presentean, presentaan
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: (presentaban OR ((presenten OR ((presentaaan OR presentan) OR presentar)) OR present))~.
• Adding a wildcard symbol may retrieve word variants: (presentaban or ((presenten or ((presentaaan or presentan) or presentar)) or present))*.
