• The words AND, OR and NOT may confuse the search; try adding quotes: "wang xiao yang ((yan sher) OR (han shen)) ((zhang minh) or (zhang ming)) hong tan ;~".
• Adding a wildcard symbol may retrieve word variants: wang xiao yang ((yan sher) OR (han shen)) ((zhang minh) or (zhang ming)) hong tan ;*.
