• If you are trying to use Boolean operators, they must be ALL CAPS: (( cong trinh ((tu danh) OR (tu manh)) va cad cam co oi viet nam ) OR ((( chuong trinh chat danh va cauc mau co soi viet nam ) OR ( chuong trinh chat hang va cau cau ((co doi) OR (cho doi)) viet nam ))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( cong trinh ((tu danh) or (tu manh)) va cad cam co oi viet nam ) or ((( chuong trinh chat danh va cauc mau co soi viet nam ) or ( chuong trinh chat hang va cau cau ((co doi) OR (cho doi)) viet nam ))))~".
• Adding a wildcard symbol may retrieve word variants: (( cong trinh ((tu danh) or (tu manh)) va cad cam co oi viet nam ) or ((( chuong trinh chat danh va cauc mau co soi viet nam ) or ( chuong trinh chat hang va cau cau ((co doi) OR (cho doi)) viet nam ))))*.
