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