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