• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu sach - ((hanh tung) OR (((hanh trinh) OR (canh tranh)))) lan hung xuong van than cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu sach - ((hanh tung) or (((hanh trinh) OR (canh tranh)))) lan hung xuong van than cau*".
