• If you are trying to use Boolean operators, they must be ALL CAPS: (( thu sach ca me gioi con hong tin ) OR ( tu ((sach cha) OR (sach ha)) ve giai con tdong tinh ))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( thu sach ca me gioi con hong tin ) or ( tu ((sach cha) OR (sach ha)) ve giai con tdong tinh ))*".
