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