• If you are trying to use Boolean operators, they must be ALL CAPS: doi chieu sang - thanh tung ((cap dung) OR (ap dung)) cong dan ((toan cau) OR (toan tap))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi chieu sang - thanh tung ((cap dung) or (ap dung)) cong dan ((toan cau) OR (toan tap))*".
