• If you are trying to use Boolean operators, they must be ALL CAPS: %((contributi alla) OR (contributi di))%((((istituto di) OR (instituto ad))) OR (istituti di)) storia romantica%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%((contributi alla) or (contributi di))%((((istituto di) OR (instituto ad))) or (istituti di)) storia romantica%22".
• Adding a wildcard symbol may retrieve word variants: %((contributi alla) or (contributi di))%((((istituto di) OR (instituto ad))) or (istituti di)) storia romantica%22*.
