• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((((chieu xanh) OR (hieu manh))) or (chieu sach)) - hanh tang cua nong cong thanh tran cau~".
• Adding a wildcard symbol may retrieve word variants: theo ((((chieu xanh) OR (hieu manh))) or (chieu sach)) - hanh tang cua nong cong thanh tran cau*.
