Perhaps you should try some spelling variations:
convegno del » convegno della, convegno di, convegno per
la republica » la republique, _ republican
governo del » gobierno del
sua zuccari » sala zuccari
senato la » sento la, senat la, senator a

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: di ((((convegno del) OR (governo del))la) OR (((convegno del) OR (governo del)))) sua zuccari / senato la republica.
• The words AND, OR and NOT may confuse the search; try adding quotes: "di ((((convegno del) OR (governo del))la) or (((convegno del) OR (governo del)))) sua zuccari / senato la republica".
• Adding a wildcard symbol may retrieve word variants: di ((((convegno del) OR (governo del))la) or (((convegno del) OR (governo del)))) sua zuccari / senato la republica*.
