Perhaps you should try some spelling variations:
historia antigua » historia antiqua
contributi dalla » contributi alla, contributo alla, contributi di
historia antiga » historia antiqua, historia argentina
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) OR (contributo della))%((istituto di) OR (instituti di)) ((historia antiga) OR (historia antigua))%22*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%((contributi dalla) or (contributo della))%((istituto di) or (instituti di)) ((historia antiga) OR (historia antigua))%22*".
