• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((chu sach) OR (thu sach)) - thanh trung tuan ((nhung cong) OR (hang cong)) dan than cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chu sach) or (thu sach)) - thanh trung tuan ((nhung cong) OR (hang cong)) dan than cau".
