• If you are trying to use Boolean operators, they must be ALL CAPS: hoc thieu tinh - hanh trang cua ((((nhung cong) OR (nhung don))) OR (dung cong)) tan toan cao*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc thieu tinh - hanh trang cua ((((nhung cong) OR (nhung don))) or (dung cong)) tan toan cao*".
