• If you are trying to use Boolean operators, they must be ALL CAPS: tu sai ky dang ((xay hoi) OR (tay hoi)). hieu ve cam ((xuc van) OR (duc manh)) hanh va cua tre~.
• Adding a wildcard symbol may retrieve word variants: tu sai ky dang ((xay hoi) or (tay hoi)). hieu ve cam ((xuc van) or (duc manh)) hanh va cua tre*.
