• If you are trying to use Boolean operators, they must be ALL CAPS: (( te sach ((cua ve) OR (cua te)) giao cong thong tin ) OR ( tu sach cha ve gia cong hoa binh ))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( te sach ((cua ve) OR (cua te)) giao cong thong tin ) or ( tu sach cha ve gia cong hoa binh ))*".
