• If you are trying to use Boolean operators, they must be ALL CAPS: doi chieu sang - ((thanh tuong) OR (thanh thuong)) cua ((khong cong) OR (chong cong)) te thanh cac*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi chieu sang - ((thanh tuong) OR (thanh thuong)) cua ((khong cong) or (chong cong)) te thanh cac*".
