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