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