• If you are trying to use Boolean operators, they must be ALL CAPS: ((tho van) OR (tho dan)) tinh - thanh trung cua dung cong san ((thang ca) OR (hang ca))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tho van) OR (tho dan)) tinh - thanh trung cua dung cong san ((thang ca) or (hang ca))*".
