• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu sach - ((hanh tranh) OR (hanh trang)) cua ((nhung phuong) OR (dung phuong)) dan toan cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu sach - ((hanh tranh) OR (hanh trang)) cua ((nhung phuong) or (dung phuong)) dan toan cau*".
