Perhaps you should try some spelling variations:
contributi dalla » contributi alla, contributo della, contributo alla
storia antica » storia romantica, historia antiga, storia critica
storia gotica » storia politica, storia critica, storia emotiva
instituti di » istituti di, instituti _, instituti a
istituto di » instituto de, instituto ad

You may be able to get more results by adjusting your search query.

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