• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((thiet anh) OR (thuyet anh)) - hanh thanh ((toan nhung) OR (toan chung)) cong san thanh chau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((thiet anh) OR (thuyet anh)) - hanh thanh ((toan nhung) or (toan chung)) cong san thanh chau*".
