• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach _ lang ha noi. hieu ((van cam) OR (van cau)) xuc van hanh ((vai cua) OR (hai cua)) tu.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach _ lang ha noi. hieu ((van cam) OR (van cau)) xuc van hanh ((vai cua) or (hai cua)) tu".
