• If you are trying to use Boolean operators, they must be ALL CAPS: wang fang zhen yuan ((((ying chang) OR (jin chang))) OR (boon chong)) chik fang (sheng OR cheng) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang fang zhen yuan ((((ying chang) OR (jin chang))) or (boon chong)) chik fang (sheng or cheng) ;~".
• Adding a wildcard symbol may retrieve word variants: wang fang zhen yuan ((((ying chang) OR (jin chang))) or (boon chong)) chik fang (sheng or cheng) ;*.
