• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((((chieu sach) OR (chinh sach))) OR (ha tinh)) - hinh trong quang dung cong dan van ban.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((((chieu sach) OR (chinh sach))) or (ha tinh)) - hinh trong quang dung cong dan van ban".
