• Performing a fuzzy search may retrieve terms with similar spellings: (( chuong trinh may doan va cac cam ((co oi) OR (co loi)) viet nam ) or ( chuong trinh may dan ca cac cap co soi viet nam ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( chuong trinh may doan va cac cam ((co oi) OR (co loi)) viet nam ) OR ( chuong trinh may dan ca cac cap co soi viet nam )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( chuong trinh may doan va cac cam ((co oi) OR (co loi)) viet nam ) or ( chuong trinh may dan ca cac cap co soi viet nam ))".
• Adding a wildcard symbol may retrieve word variants: (( chuong trinh may doan va cac cam ((co oi) OR (co loi)) viet nam ) or ( chuong trinh may dan ca cac cap co soi viet nam ))*.
