• If you are trying to use Boolean operators, they must be ALL CAPS: theo chu xanh - hanh ((((trinh va) OR (trinh vat))) OR (trinh ve)) hang cong dang van ban.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chu xanh - hanh ((((trinh va) OR (trinh vat))) or (trinh ve)) hang cong dang van ban".
