• If you are trying to use Boolean operators, they must be ALL CAPS: (( te sach ha ve giai con hong tin ) OR ( te sach ha ((ve giao) OR (viet giao)) cong hong minh ))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( te sach ha ve giai con hong tin ) or ( te sach ha ((ve giao) OR (viet giao)) cong hong minh ))*".
