• If you are trying to use Boolean operators, they must be ALL CAPS: theo chieu tinh - ((hanh trung) OR (manh trung)) cua ((hang cong) OR (dang cong)) dan toan ban.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chieu tinh - ((hanh trung) or (manh trung)) cua ((hang cong) OR (dang cong)) dan toan ban".
• Adding a wildcard symbol may retrieve word variants: theo chieu tinh - ((hanh trung) or (manh trung)) cua ((hang cong) OR (dang cong)) dan toan ban*.
