• If you are trying to use Boolean operators, they must be ALL CAPS: (( ((i und) OR (1 und)) libro e literatur greca ) OR ( i grunde die la letteratura storia )).
• Adding a wildcard symbol may retrieve word variants: (( ((i und) or (1 und)) libro e literatur greca ) or ( i grunde die la letteratura storia ))*.
