• The words AND, OR and NOT may confuse the search; try adding quotes: "zhang ying coding alan best ((zhang ping) OR (zhang jing)) ((kong young) or (dong sin)) ;~".
• Adding a wildcard symbol may retrieve word variants: zhang ying coding alan best ((zhang ping) OR (zhang jing)) ((kong young) or (dong sin)) ;*.
