• If you are trying to use Boolean operators, they must be ALL CAPS: hoc thieu sang - canh tranh ((cua khong) OR (xuan truong)) cong van ((thanh tai) OR (thanh toan))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc thieu sang - canh tranh ((cua khong) or (xuan truong)) cong van ((thanh tai) OR (thanh toan))*".
