yang yao » yang yang, wang yan, yang yi
yang fan » zhang fan, yang dean, yang yang
demand a » demand _, demand 3, demand 1

gg 3 » gg b, ag 3, gg 2

• If you are trying to use Boolean operators, they must be ALL CAPS: ((((yang yao) OR (yang fan))) OR (yang di))gg 3 human demand a min hong guan ;~.
• Adding a wildcard symbol may retrieve word variants: ((((yang yao) or (yang fan))) or (yang di))gg 3 human demand a min hong guan ;*.
