• The words AND, OR and NOT may confuse the search; try adding quotes: "((liang wang) OR (liang ying)) yang ((juan rene) or (juan meng)) pang can dang hai ;~".
• Adding a wildcard symbol may retrieve word variants: ((liang wang) OR (liang ying)) yang ((juan rene) or (juan meng)) pang can dang hai ;*.
