• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sac) OR (su cac)) ky nang x ho. hieu van bac xuc va hanh ((thai cua) OR (tri cua)) triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sac) or (su cac)) ky nang x ho. hieu van bac xuc va hanh ((thai cua) OR (tri cua)) triet".
