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