• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach so lang ((va hoe) OR (va hoa)). hieu va cac luc van hanh vai ((cua te) OR (cua chu))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach so lang ((va hoe) OR (va hoa)). hieu va cac luc van hanh vai ((cua te) or (cua chu))*".
