• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu sang - ((doanh ban) OR (doanh van)) cua nhung ((song van) OR (luong va)) toan tap*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu sang - ((doanh ban) OR (doanh van)) cua nhung ((song van) or (luong va)) toan tap*".
