• If you are trying to use Boolean operators, they must be ALL CAPS: hoc chieu sang - canh thanh van dung cong ((dong van) OR (((duong van) OR (luong va)))) ban*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc chieu sang - canh thanh van dung cong ((dong van) or (((duong van) OR (luong va)))) ban*".
