• If you are trying to use Boolean operators, they must be ALL CAPS: ((thu sai) OR (thu hai)) ky nang x hoi. hieu va cam xuc ((va hanh) OR (va thanh)) vai cua te.

• Adding a wildcard symbol may retrieve word variants: ((thu sai) or (thu hai)) ky nang x hoi. hieu va cam xuc ((va hanh) OR (va thanh)) vai cua te*.
