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