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