Perhaps you should try some spelling variations:
governo della » governo del, governo de
convegno del » convegno della, convegno di, convegno per
de republica » la republica, _ republican, a republican
succinte de » succincte de, succincte des, succinct de
zuccari » zaccaria

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "i ((governo della) OR (convegno del)) sala zuccari / succinte de republica".
• Adding a wildcard symbol may retrieve word variants: i ((governo della) OR (convegno del)) sala zuccari / succinte de republica*.
