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