• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) or (doi chieu)) tinh - hanh tang cua phuong cong dan ((toan cau) OR (toan ban))~".
• Adding a wildcard symbol may retrieve word variants: ((ho chieu) or (doi chieu)) tinh - hanh tang cua phuong cong dan ((toan cau) OR (toan ban))*.
