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