• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang wang) OR (wang yang)) yan guan jang yang ((xi kang) OR (jin kang)) han ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang wang) or (wang yang)) yan guan jang yang ((xi kang) OR (jin kang)) han ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang wang) or (wang yang)) yan guan jang yang ((xi kang) OR (jin kang)) han ;*.
