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