• If you are trying to use Boolean operators, they must be ALL CAPS: te cac ((ky lang) OR (ky nang)) xa hoi. ((hieu va) OR (lieu va)) cham loc va danh vai cua tre.

• Adding a wildcard symbol may retrieve word variants: te cac ((ky lang) or (ky nang)) xa hoi. ((hieu va) OR (lieu va)) cham loc va danh vai cua tre*.
