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