• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ((y nang) OR (v nang)) cao hoc. hieu va cham xuc ((va dinh) OR (va dan)) dai cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((y nang) OR (v nang)) cao hoc. hieu va cham xuc ((va dinh) or (va dan)) dai cua te".
