• If you are trying to use Boolean operators, they must be ALL CAPS: when you liang wei reformen ((jan david) OR (sahn david)) ((hong g) OR (dang hai)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "when you liang wei reformen ((jan david) OR (sahn david)) ((hong g) or (dang hai)) ;~".
• Adding a wildcard symbol may retrieve word variants: when you liang wei reformen ((jan david) OR (sahn david)) ((hong g) or (dang hai)) ;*.
