Perhaps you should try some spelling variations:
presenteed » presentee, presentees, presenteen, presenteeed, presentaeed
presented » presente, presenta, presentan, presenteed, presentaed
presentaron » presentacion, presentation, presentan, presentearon, presentaaron
presentare » presentarse, presentarle, presentar, presenteare, presentaare
presentaar » presentar, presentadas, presentaban, presenteaar, presentaaar
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: ((presenteed OR presented) OR ((presentaron OR (presentare OR presentaar)) OR present))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((presenteed OR presented) or ((presentaron or (presentare or presentaar)) or present))~".
• Adding a wildcard symbol may retrieve word variants: ((presenteed OR presented) or ((presentaron or (presentare or presentaar)) or present))*.
