• If you are trying to use Boolean operators, they must be ALL CAPS: ((hoc chieu) OR (ho chieu)) sach - ((hanh trang) OR (canh tranh)) cua hang cong tap toan ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc chieu) or (ho chieu)) sach - ((hanh trang) OR (canh tranh)) cua hang cong tap toan ban~".
• Adding a wildcard symbol may retrieve word variants: ((hoc chieu) or (ho chieu)) sach - ((hanh trang) OR (canh tranh)) cua hang cong tap toan ban*.
