Perhaps you should try some spelling variations:
presented » presente, presenta, presenteed, presentaed
presentan » presenta, presente, presentacion, presentean, presentaan
presents » presente, presenta, presentes, presentas
presentaran » presentaron, presentaban, presentara, presentearan, presentaaran
presentear » presentar, presenter, presente, presenteear, presentaear
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: ((presented OR presentan) OR ((presents OR (presentaran OR presentear)) OR present))~.
• Adding a wildcard symbol may retrieve word variants: ((presented or presentan) or ((presents or (presentaran or presentear)) or present))*.
