• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((hieu quang) OR (chau tinh)) - thanh trung cua nhua phuong ((doan toan) OR (doan tuan)) cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((hieu quang) or (chau tinh)) - thanh trung cua nhua phuong ((doan toan) OR (doan tuan)) cau~".
• Adding a wildcard symbol may retrieve word variants: theo ((hieu quang) or (chau tinh)) - thanh trung cua nhua phuong ((doan toan) OR (doan tuan)) cau*.
