• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu xanh) OR (chieu sach)) - thanh truong chuong duong cong ((tac chan) OR (tac chuan)) cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu xanh) or (chieu sach)) - thanh truong chuong duong cong ((tac chan) OR (tac chuan)) cau".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu xanh) or (chieu sach)) - thanh truong chuong duong cong ((tac chan) OR (tac chuan)) cau*.
