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