• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((((chieu xanh) OR (chieu sach))) OR (chieu sang)) - hanh tang luan dung cong tac thanh cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((((chieu xanh) OR (chieu sach))) or (chieu sang)) - hanh tang luan dung cong tac thanh cau~".
• Adding a wildcard symbol may retrieve word variants: hoc ((((chieu xanh) OR (chieu sach))) or (chieu sang)) - hanh tang luan dung cong tac thanh cau*.
