• If you are trying to use Boolean operators, they must be ALL CAPS: doi chi sach - hanh ((((trang vap) OR (trang van))) OR (tran van)) truong phuong danh toan cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi chi sach - hanh ((((trang vap) OR (trang van))) or (tran van)) truong phuong danh toan cau*".
