• If you are trying to use Boolean operators, they must be ALL CAPS: (wang OR wing) ((yan ching) OR (ya ching)) hei sing ((huang kong) OR (hong kong)) chong yah ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(wang or wing) ((yan ching) or (ya ching)) hei sing ((huang kong) OR (hong kong)) chong yah ;~".
• Adding a wildcard symbol may retrieve word variants: (wang or wing) ((yan ching) or (ya ching)) hei sing ((huang kong) OR (hong kong)) chong yah ;*.
