Perhaps you should try some spelling variations:
presented » presente, presenta, presenteed, presentaed
presentan » presenta, presente, presentacion, presentean, presentaan
presents » presente, presenta, presentes, presentas
presentada » presentado, presenta, presentar, presenteada, presentaada
presentaada » presentadasa, presentado, presentando, presenteaada, presentaaada
presentaea » presentara, presentata, presentadas, presenteaea, presentaaea
presentaba » presentaban, presentara, presentadas, presenteaba, presentaaba
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 (presentada OR presentaada))) OR (presentaea OR presentaba)) OR present))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(presented or (((presentan or (presents or (presentada OR presentaada))) or (presentaea or presentaba)) or present))~".
• Adding a wildcard symbol may retrieve word variants: (presented or (((presentan or (presents or (presentada OR presentaada))) or (presentaea or presentaba)) or present))*.
