vu sach » vu bach, su sach, vu khach
so van » su van, vo van
va cua » va chua, via cua, ca cua
ve cac » va cac, vien cac
x hoi » xa hoi, o hoi, x ho

• If you are trying to use Boolean operators, they must be ALL CAPS: ((so sanh) OR (vu sach)) ky nang x hoi. hieu ve cac ((lo va) OR (so van)) hang va cua tre~.
• Adding a wildcard symbol may retrieve word variants: ((so sanh) or (vu sach)) ky nang x hoi. hieu ve cac ((lo va) or (so van)) hang va cua tre*.
