• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu tinh - ((((hanh trang) OR (hanh trinh))) OR (canh tranh)) cua dung cong dan than ban.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu tinh - ((((hanh trang) OR (hanh trinh))) or (canh tranh)) cua dung cong dan than ban".
