• If you are trying to use Boolean operators, they must be ALL CAPS: (( chuong trinh cac ((lanh va) OR (doanh va)) cac tap co soi viet nam ) OR ( chuong trinh chao lanh dao cao cap do ((choi viet) OR (hoi viet)) nam ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( chuong trinh cac ((lanh va) OR (doanh va)) cac tap co soi viet nam ) or ( chuong trinh chao lanh dao cao cap do ((choi viet) or (hoi viet)) nam ))~".
• Adding a wildcard symbol may retrieve word variants: (( chuong trinh cac ((lanh va) OR (doanh va)) cac tap co soi viet nam ) or ( chuong trinh chao lanh dao cao cap do ((choi viet) or (hoi viet)) nam ))*.
