• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((chieu xanh) OR (chiet tach)) - hanh trang cua ((nhung huong) OR (nhung cong)) tinh toan ban.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((chieu xanh) or (chiet tach)) - hanh trang cua ((nhung huong) OR (nhung cong)) tinh toan ban".
