• If you are trying to use Boolean operators, they must be ALL CAPS: su sai ky nang ma hoi. hieu ((va cam) OR (ve cac)) ((luc va) OR (duc va)) hang di cua tre.
• Adding a wildcard symbol may retrieve word variants: su sai ky nang ma hoi. hieu ((va cam) or (ve cac)) ((luc va) or (duc va)) hang di cua tre*.
