presentada » presenta, presentar, presenteada, presentaada
presentaron » presentacion, presentation, presentarse, presentearon, presentaaron
presented » presente, presenta, presenteed, presentaed

• If you are trying to use Boolean operators, they must be ALL CAPS: ((presentado OR presentada) OR ((presentaron OR (presented OR presentan)) OR present))~.
• Adding a wildcard symbol may retrieve word variants: ((presentado or presentada) or ((presentaron or (presented or presentan)) or present))*.
