• If you are trying to use Boolean operators, they must be ALL CAPS: ((yang sheng) OR (wang yuhan)) ((jing ta) OR (jing jia)) china chang fong wang zhi ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((yang sheng) or (wang yuhan)) ((jing ta) OR (jing jia)) china chang fong wang zhi ;~".
• Adding a wildcard symbol may retrieve word variants: ((yang sheng) or (wang yuhan)) ((jing ta) OR (jing jia)) china chang fong wang zhi ;*.
