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