• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho lieu) or (ho kieu)) tinh - thanh trung cua thong cong thanh ((thang cap) OR (thong cap))~".
• Adding a wildcard symbol may retrieve word variants: ((ho lieu) or (ho kieu)) tinh - thanh trung cua thong cong thanh ((thang cap) OR (thong cap))*.
