• If you are trying to use Boolean operators, they must be ALL CAPS: (( chuong trinh chat anh va ((((cac nam) OR (bac nam))) OR (cac cam)) co so viet nam ) OR ( cong ((trinh cham) OR (trinh phan)) binh va cac ((cau co) OR (cac co)) cuoi viet nam ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( chuong trinh chat anh va ((((cac nam) or (bac nam))) or (cac cam)) co so viet nam ) or ( cong ((trinh cham) OR (trinh phan)) binh va cac ((cau co) or (cac co)) cuoi viet nam ))~".
• Adding a wildcard symbol may retrieve word variants: (( chuong trinh chat anh va ((((cac nam) or (bac nam))) or (cac cam)) co so viet nam ) or ( cong ((trinh cham) OR (trinh phan)) binh va cac ((cau co) or (cac co)) cuoi viet nam ))*.
