• If you are trying to use Boolean operators, they must be ALL CAPS: (( tinh luong quan van hieu qua ) OR ( tin nang ((quan binh) OR (quang ninh)) hien soat ))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( tinh luong quan van hieu qua ) or ( tin nang ((quan binh) OR (quang ninh)) hien soat ))*".
