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