thong huong » thong thuong, thong duong, thong thong
hien nhanh » hien hanh, tien thanh, dien thanh
thang he » tang he, thang nghe, thang nho

• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((thien thanh) OR (hien nhanh)) - thanh thang he thong huong ((dan toan) OR (van toan)) cao*.
