• If you are trying to use Boolean operators, they must be ALL CAPS: (( tu sach ha de giai cong thuong hieu ) OR ( vu ((bach cha) OR (bach ha)) ve gioi co hong tin ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( tu sach ha de giai cong thuong hieu ) or ( vu ((bach cha) OR (bach ha)) ve gioi co hong tin ))~".
• Adding a wildcard symbol may retrieve word variants: (( tu sach ha de giai cong thuong hieu ) or ( vu ((bach cha) OR (bach ha)) ve gioi co hong tin ))*.
