• If you are trying to use Boolean operators, they must be ALL CAPS: wan hyoung ((((((yan yuan) OR (fang yuan))) OR (yang yue))) OR (nan yan)) tan yang xi cheng chen ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wan hyoung ((((((yan yuan) OR (fang yuan))) or (yang yue))) or (nan yan)) tan yang xi cheng chen ;~".
• Adding a wildcard symbol may retrieve word variants: wan hyoung ((((((yan yuan) OR (fang yuan))) or (yang yue))) or (nan yan)) tan yang xi cheng chen ;*.
