• If you are trying to use Boolean operators, they must be ALL CAPS: (( cong trinh cuu anh va cac tro co soi viet nam ) OR ((( chuong trinh chat lanh ((do bac) OR (do ban)) cau do moi viet nam ) OR ( chuong trinh cac lanh co cac cau do hoi viet nam ))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( cong trinh cuu anh va cac tro co soi viet nam ) or ((( chuong trinh chat lanh ((do bac) OR (do ban)) cau do moi viet nam ) or ( chuong trinh cac lanh co cac cau do hoi viet nam ))))~".
