dong bin » dong sin, dong di, dann bin
dong cao » dong xiao, dan cao, dong nan
jiu wong » jiu cong, ji won, kie wong
wong siu » wong shiu, kong siu, wong sau
test a » test _, test 4, test 5
a jiu » a iu
ya a » a a, y a, ye a

• If you are trying to use Boolean operators, they must be ALL CAPS: ((((dong bin) OR (dong cao))) OR (((wang liang) OR (wang yang)))) ya a test a jiu wong siu ;.
• Adding a wildcard symbol may retrieve word variants: ((((dong bin) or (dong cao))) or (((wang liang) or (wang yang)))) ya a test a jiu wong siu ;*.
