• If you are trying to use Boolean operators, they must be ALL CAPS: ((yan liang) OR (((yuan wang) OR (yuan chang)))) tan ((hua rene) OR (hua ren)) yang jun wong yue ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((yan liang) or (((yuan wang) OR (yuan chang)))) tan ((hua rene) or (hua ren)) yang jun wong yue ;~".
• Adding a wildcard symbol may retrieve word variants: ((yan liang) or (((yuan wang) OR (yuan chang)))) tan ((hua rene) or (hua ren)) yang jun wong yue ;*.
