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