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