Perhaps you should try some spelling variations:
contributi dalla » contributi alla, contributo della, contributi di
historia antigua » historia antiqua
contributo alla » contributi alla, contributo allo, contributo della
historia antiga » historia antiqua, historia argentina
instituto ad » instituto de, instituto _, institutos de
istituti di » instituti di, istituto di, istituti pii

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