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