• If you are trying to use Boolean operators, they must be ALL CAPS: ((ho chiet) OR (hoc thiet)) tach - hanh trang cua nhung ((cong van) OR (cong san)) toan tap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chiet) OR (hoc thiet)) tach - hanh trang cua nhung ((cong van) or (cong san)) toan tap~".
• Adding a wildcard symbol may retrieve word variants: ((ho chiet) OR (hoc thiet)) tach - hanh trang cua nhung ((cong van) or (cong san)) toan tap*.
