• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (su sach)) ky ((nang xa) OR (nang ma)) hoi. hieu va cam suc manh hanh lai cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) or (su sach)) ky ((nang xa) OR (nang ma)) hoi. hieu va cam suc manh hanh lai cua tre*".
