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