• If you are trying to use Boolean operators, they must be ALL CAPS: hoc thieu xanh - canh tranh cam nang cong ((((danh toan) OR (anh toan))) OR (manh toan)) cao*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc thieu xanh - canh tranh cam nang cong ((((danh toan) OR (anh toan))) or (manh toan)) cao*".
