• Performing a fuzzy search may retrieve terms with similar spellings: hoc chieu sach - hanh trang va dung ((trong san) OR (cong san)) ((than cap) or (toan tap))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: hoc chieu sach - hanh trang va dung ((trong san) OR (cong san)) ((than cap) OR (toan tap))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc chieu sach - hanh trang va dung ((trong san) OR (cong san)) ((than cap) or (toan tap))*".
