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