• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu sang - ((((thanh thanh) OR (thanh phan))) OR (nhanh thanh)) va nhung cong san toan cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu sang - ((((thanh thanh) OR (thanh phan))) or (nhanh thanh)) va nhung cong san toan cau*".
