• If you are trying to use Boolean operators, they must be ALL CAPS: ((doc sach) OR (nuoc sach)) lo cong tac noi. hieu va cham xuc ((va dan) OR (gia dinh)) vi cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((doc sach) OR (nuoc sach)) lo cong tac noi. hieu va cham xuc ((va dan) or (gia dinh)) vi cua te".
