• If you are trying to use Boolean operators, they must be ALL CAPS: wang wang ((yang hua) OR (ying hua)) tan ying jie ((shang kai) OR (((hong hong) OR (hong ng)))) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang wang ((yang hua) OR (ying hua)) tan ying jie ((shang kai) or (((hong hong) or (hong ng)))) ;~".
• Adding a wildcard symbol may retrieve word variants: wang wang ((yang hua) OR (ying hua)) tan ying jie ((shang kai) or (((hong hong) or (hong ng)))) ;*.
