• If you are trying to use Boolean operators, they must be ALL CAPS: doi ((chieu xanh) OR (((chieu sach) OR (chieu sang)))) - thanh trung cua cong cong lang toan ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi ((chieu xanh) or (((chieu sach) OR (chieu sang)))) - thanh trung cua cong cong lang toan ban~".
• Adding a wildcard symbol may retrieve word variants: doi ((chieu xanh) or (((chieu sach) OR (chieu sang)))) - thanh trung cua cong cong lang toan ban*.
