• Performing a fuzzy search may retrieve terms with similar spellings: hoc ((chinh sach) or (chiet tach)) - hanh trang cua truong cuong tap ((vat ban) OR (vat ran))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((chinh sach) OR (chiet tach)) - hanh trang cua truong cuong tap ((vat ban) OR (vat ran))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((chinh sach) or (chiet tach)) - hanh trang cua truong cuong tap ((vat ban) OR (vat ran))*".
