yang yang » wang yang, wang yan
dann bin » dong bin
sub band » zu band
band kan » band gap
thi hong » tan hong
kan thi » tran thi, dang thi, nhan thi
hong ma » hong a, hong tan, hong hai

• If you are trying to use Boolean operators, they must be ALL CAPS: ((dann bin) OR (((yang yang) OR (wang liang)))) ya sub band kan thi hong ma ;*.
