Perhaps you should try some spelling variations:
contributi dalla » contributi alla, contributo della, contributi di
contributo alla » contributi alla, contributo allo, contributo della
storia antica » storia gotica, storia romantica, historia antiga
instituto ad » instituto _, institutos de
instituto de » institut der, institution der
istituti di » instituti di, istituti pii, 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) OR (contributo alla))%((((((istituto di) OR (instituto ad))) OR (instituto de))) OR (istituti di)) storia antica%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%((contributi dalla) OR (contributo alla))%((((((istituto di) or (instituto ad))) or (instituto de))) or (istituti di)) storia antica%22".
• Adding a wildcard symbol may retrieve word variants: %((contributi dalla) OR (contributo alla))%((((((istituto di) or (instituto ad))) or (instituto de))) or (istituti di)) storia antica%22*.
