• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu sach - ((canh hoang) OR (ctnhh hoang)) van dung cong san ((phan dau) OR (phan cac))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu sach - ((canh hoang) OR (ctnhh hoang)) van dung cong san ((phan dau) or (phan cac))*".
