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