• If you are trying to use Boolean operators, they must be ALL CAPS: dann jia zhang run ((pains long) OR (kim song)) jing ((fang yue) OR (wang yue)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "dann jia zhang run ((pains long) or (kim song)) jing ((fang yue) OR (wang yue)) ;~".
• Adding a wildcard symbol may retrieve word variants: dann jia zhang run ((pains long) or (kim song)) jing ((fang yue) OR (wang yue)) ;*.
