• The words AND, OR and NOT may confuse the search; try adding quotes: "%contributi dalla%((((istituto di) or (instituto de))) or (istituti di)) ((storia antica) OR (storia romantica))%22".
• Adding a wildcard symbol may retrieve word variants: %contributi dalla%((((istituto di) or (instituto de))) or (istituti di)) ((storia antica) OR (storia romantica))%22*.
