• If you are trying to use Boolean operators, they must be ALL CAPS: su ((sac ky) OR (sach y)) nang ma hoa. lieu ((va bao) OR (va cac)) xuc va thanh vi su triet.
• Adding a wildcard symbol may retrieve word variants: su ((sac ky) or (sach y)) nang ma hoa. lieu ((va bao) or (va cac)) xuc va thanh vi su triet*.
