• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang OR wing) OR lang) ((yan yuan) OR (yan guan)) ((li chen) OR (yi chen)) zhen xin jeong shu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang or wing) or lang) ((yan yuan) OR (yan guan)) ((li chen) or (yi chen)) zhen xin jeong shu ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang or wing) or lang) ((yan yuan) OR (yan guan)) ((li chen) or (yi chen)) zhen xin jeong shu ;*.
