• If you are trying to use Boolean operators, they must be ALL CAPS: ho chiet tach - ((hanh dung) OR (anh dung)) luan nhung cong tac ((doan ban) OR (toan ban))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chiet tach - ((hanh dung) OR (anh dung)) luan nhung cong tac ((doan ban) or (toan ban))*".
