• If you are trying to use Boolean operators, they must be ALL CAPS: doi chieu xanh - ((hanh trang) OR (hanh chinh)) cua khong cong ((dan than) OR (van than)) tap*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi chieu xanh - ((hanh trang) or (hanh chinh)) cua khong cong ((dan than) OR (van than)) tap*".
