fan ying » fan xing, ran ying, tan ying
ying jun » yang jun, ying jin, yang jui

• If you are trying to use Boolean operators, they must be ALL CAPS: dong yang ka othman fan ying jun ((hong hai) OR (dang hai)) ;~.
• Adding a wildcard symbol may retrieve word variants: dong yang ka othman fan ying jun ((hong hai) or (dang hai)) ;*.
