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