• If you are trying to use Boolean operators, they must be ALL CAPS: doi chieu sach - ((danh trung) OR (hanh trang)) cua dung phuong ((doan than) OR (doan tuan)) cap*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi chieu sach - ((danh trung) or (hanh trang)) cua dung phuong ((doan than) OR (doan tuan)) cap*".
