• If you are trying to use Boolean operators, they must be ALL CAPS: hoc thieu tinh - ((((hanh trung) OR (hanh trang))) OR (manh trung)) cap hang cong trinh toan ban*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc thieu tinh - ((((hanh trung) OR (hanh trang))) or (manh trung)) cap hang cong trinh toan ban*".
