• If you are trying to use Boolean operators, they must be ALL CAPS: doi ((chieu xanh) OR (chieu sach)) - nhan dong va nhung cong dan ((than cap) OR (han tap))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi ((chieu xanh) OR (chieu sach)) - nhan dong va nhung cong dan ((than cap) or (han tap))*".
