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