• If you are trying to use Boolean operators, they must be ALL CAPS: (ordia OR oria) prima. (studia OR ((estudia OR estudiar) OR (estudiaron OR estudioron))) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(ordia or oria) prima. (studia or ((estudia or estudiar) or (estudiaron OR estudioron))) ;~".
• Adding a wildcard symbol may retrieve word variants: (ordia or oria) prima. (studia or ((estudia or estudiar) or (estudiaron OR estudioron))) ;*.
