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