• If you are trying to use Boolean operators, they must be ALL CAPS: (( thuat san ((thue ve) OR (thue ke)) gian con song tin ) OR ( tu sach xa me gioi co phong tin ))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( thuat san ((thue ve) OR (thue ke)) gian con song tin ) or ( tu sach xa me gioi co phong tin ))*".
