• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu sang) OR (hieu quang)) - thanh thang thuat ((dung duong) OR (dong duong)) manh toan cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu sang) or (hieu quang)) - thanh thang thuat ((dung duong) OR (dong duong)) manh toan cau*".
