• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((chieu xanh) OR (chieu sach)) - hanh trung ha ((nhung cong) OR (thong cong)) ban phan cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chieu xanh) OR (chieu sach)) - hanh trung ha ((nhung cong) or (thong cong)) ban phan cau*".
