• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu sach - hanh ((tang cua) or (hang cua)) nhung cong ((van thanh) OR (van tuan)) chau~".
• Adding a wildcard symbol may retrieve word variants: ho chieu sach - hanh ((tang cua) or (hang cua)) nhung cong ((van thanh) OR (van tuan)) chau*.
