• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chu xanh - hanh tang cua thuong ((cong dan) or (cong tan)) ((than cau) OR (toan cau))~".
• Adding a wildcard symbol may retrieve word variants: theo chu xanh - hanh tang cua thuong ((cong dan) or (cong tan)) ((than cau) OR (toan cau))*.
