• The words AND, OR and NOT may confuse the search; try adding quotes: "zhang ying ((tan chen) or (tan cheng)) tan yang guang ((cheng mae) OR (cheng jay)) ;~".
• Adding a wildcard symbol may retrieve word variants: zhang ying ((tan chen) or (tan cheng)) tan yang guang ((cheng mae) OR (cheng jay)) ;*.
