• If you are trying to use Boolean operators, they must be ALL CAPS: chuong trinh ca ((anh va) OR (hanh va)) cac ((cam co) OR (((cay co) OR (cay cong)))) soi viet nam*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "chuong trinh ca ((anh va) or (hanh va)) cac ((cam co) or (((cay co) OR (cay cong)))) soi viet nam*".
