• If you are trying to use Boolean operators, they must be ALL CAPS: (( tu ((sach che) OR (sach nha)) me giai con dong tien ) OR ( tu sach bai ve gioi co pdong tin ))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( tu ((sach che) OR (sach nha)) me giai con dong tien ) or ( tu sach bai ve gioi co pdong tin ))*".
