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