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