yan wann » yan wang, yuan wang
kong eiu » tonga eiu
dong bin » dong sin, dong di, dann bin
wai yan » wang yan, wei yang

• If you are trying to use Boolean operators, they must be ALL CAPS: wai yan wann yu ((cheng ying) OR (cheng ling)) jin ((cong shu) OR (((kong eiu) OR (dong bin)))) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wai yan wann yu ((cheng ying) OR (cheng ling)) jin ((cong shu) or (((kong eiu) or (dong bin)))) ;*".
