• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((thien hach) OR (((chieu sach) OR (chiet tach)))) - hanh trang cua dung cong san thanh cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((thien hach) or (((chieu sach) OR (chiet tach)))) - hanh trang cua dung cong san thanh cau~".
• Adding a wildcard symbol may retrieve word variants: hoc ((thien hach) or (((chieu sach) OR (chiet tach)))) - hanh trang cua dung cong san thanh cau*.
