Perhaps you should try some spelling variations:
presentaban » presentan, presentaron, presentada, presenteban
presenteron » presentaron, presenten, presentaran
presented » presente, present, presentan
presentaaan » presentaran, presentarian, presentan, presenteaan
presentar » presentan, presentarse, presente, presenter
presenta » 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: ((presentaban OR presenteron) OR ((presented OR (presentaaan OR presentar)) OR presenta))~.
• Adding a wildcard symbol may retrieve word variants: ((presentaban or presenteron) or ((presented or (presentaaan or presentar)) or presenta))*.
