• If you are trying to use Boolean operators, they must be ALL CAPS: wang qian wang ((((yuan cheng) OR (tan cheng))) OR (yuan chang)) guan kong wang zhi ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang qian wang ((((yuan cheng) OR (tan cheng))) or (yuan chang)) guan kong wang zhi ;~".
• Adding a wildcard symbol may retrieve word variants: wang qian wang ((((yuan cheng) OR (tan cheng))) or (yuan chang)) guan kong wang zhi ;*.
