• If you are trying to use Boolean operators, they must be ALL CAPS: wang zheng ((((tuan hua) OR (tan hua))) OR (wang hua)) ren change john song sau ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang zheng ((((tuan hua) OR (tan hua))) or (wang hua)) ren change john song sau ;~".
• Adding a wildcard symbol may retrieve word variants: wang zheng ((((tuan hua) OR (tan hua))) or (wang hua)) ren change john song sau ;*.
