test tuan » test tube
tuan mine » tuan minh, yuan ming
mine hong » min hong, tin hong, amin hong
hong ghi » zhong zhi, hong g, hong hai
yang yi » yang di, yang xi, yang jui

• If you are trying to use Boolean operators, they must be ALL CAPS: wang yang ((yang yi) OR (yang july)) test tuan mine hong ghi ;~.
• Adding a wildcard symbol may retrieve word variants: wang yang ((yang yi) or (yang july)) test tuan mine hong ghi ;*.
