• If you are trying to use Boolean operators, they must be ALL CAPS: doi co sach - ((thanh trung) OR (canh tranh)) cua hang ((cong dan) OR (cong tan)) toan cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi co sach - ((thanh trung) or (canh tranh)) cua hang ((cong dan) OR (cong tan)) toan cau*".
