liang sun » liang dan, liang tan
yang zili » yang dali
wing sun » cong sun, nina sun, wing ian
yang li » yang lin, yang xi, yang yi
using w » using _, using a, using 1
kong » long, hong, pong
sar » sara, star, saur

• If you are trying to use Boolean operators, they must be ALL CAPS: ((wing sun) OR (liang sun)) ((((yang zili) OR (yang li))) OR (yang di)) tests using w kong sar ;.
• Adding a wildcard symbol may retrieve word variants: ((wing sun) or (liang sun)) ((((yang zili) or (yang li))) or (yang di)) tests using w kong sar ;*.
