Perhaps you should try some spelling variations:
contributi dalla » contributi alla, contributo della, contributo alla
storia antica » storia gotica, storia romantica, historia antiga
instituto ad » instituto _, institutos de
instituto de » institut der, institution der
istituti pii » istituiti sic, istituto di, instituti di
istituti di » instituti di, istituto di, istituiti sic

Try widening your search to All Fields.

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