• Performing a fuzzy search may retrieve terms with similar spellings: (((("thi giang van tien thu") or ((((((("pho gian van tuan thu") OR ("thoi gian van tuan thu"))) or ("pho gian vung tuan thu"))) or ("pho gian dan van thuc"))))) or ((("pho cac qua ap cua") or ((("ho san lan dieu cua") or ("pham sach han kiem tra"))))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((("thi giang van tien thu") OR ((((((("pho gian van tuan thu") OR ("thoi gian van tuan thu"))) OR ("pho gian vung tuan thu"))) OR ("pho gian dan van thuc"))))) OR ((("pho cac qua ap cua") OR ((("ho san lan dieu cua") OR ("pham sach han kiem tra"))))))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"thi giang van tien thu\") or (((((((\"pho gian van tuan thu\") OR (\"thoi gian van tuan thu\"))) or (\"pho gian vung tuan thu\"))) or (\"pho gian dan van thuc\"))))) or (((\"pho cac qua ap cua\") or (((\"ho san lan dieu cua\") or (\"pham sach han kiem tra\"))))))*".
