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