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