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