• If you are trying to use Boolean operators, they must be ALL CAPS: wang yang liu yan yi gang xi ((fang zhen) OR (((wang zhenpo) OR (wang zheng)))) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yang liu yan yi gang xi ((fang zhen) or (((wang zhenpo) OR (wang zheng)))) ;~".
• Adding a wildcard symbol may retrieve word variants: wang yang liu yan yi gang xi ((fang zhen) or (((wang zhenpo) OR (wang zheng)))) ;*.
