• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((((chiet tach) OR (chieu sach))) OR (cuu tinh)) - hanh dung cua nhung cong dan than tap.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((((chiet tach) OR (chieu sach))) or (cuu tinh)) - hanh dung cua nhung cong dan than tap".
