• If you are trying to use Boolean operators, they must be ALL CAPS: (( chuong trinh cac anh va cac cap do moi viet nam ) OR ( chuong trinh cac ban va cac cac ((cot soi) OR (cot loi)) viet nam ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( chuong trinh cac anh va cac cap do moi viet nam ) or ( chuong trinh cac ban va cac cac ((cot soi) OR (cot loi)) viet nam ))~".
• Adding a wildcard symbol may retrieve word variants: (( chuong trinh cac anh va cac cap do moi viet nam ) or ( chuong trinh cac ban va cac cac ((cot soi) OR (cot loi)) viet nam ))*.
