• If you are trying to use Boolean operators, they must be ALL CAPS: (((wang OR wan) yan) OR (dan yang)) ((yan juan) OR (yan yuan)) rene yang jie song sau ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((wang OR wan) yan) or (dan yang)) ((yan juan) or (yan yuan)) rene yang jie song sau ;~".
• Adding a wildcard symbol may retrieve word variants: (((wang OR wan) yan) or (dan yang)) ((yan juan) or (yan yuan)) rene yang jie song sau ;*.
