• The words AND, OR and NOT may confuse the search; try adding quotes: "30 trieu tinh - hanh manh cua thong ((cong tan) OR (cong tac)) ((quan cau) or (quan ha))~".
• Adding a wildcard symbol may retrieve word variants: 30 trieu tinh - hanh manh cua thong ((cong tan) OR (cong tac)) ((quan cau) or (quan ha))*.
