• If you are trying to use Boolean operators, they must be ALL CAPS: wang yuan wang ((hua chen) OR (jui chen)) ((yan liang) OR (((yang jie) OR (yang jin)))) dong sin ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yuan wang ((hua chen) OR (jui chen)) ((yan liang) or (((yang jie) or (yang jin)))) dong sin ;~".
• Adding a wildcard symbol may retrieve word variants: wang yuan wang ((hua chen) OR (jui chen)) ((yan liang) or (((yang jie) or (yang jin)))) dong sin ;*.
