• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky nang ma hoi. hieu ((ve cac) OR (vien bach)) xuc ((va dinh) OR (van dinh)) co cua tu.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky nang ma hoi. hieu ((ve cac) or (vien bach)) xuc ((va dinh) OR (van dinh)) co cua tu".
