• Performing a fuzzy search may retrieve terms with similar spellings: hoc chieu sach - ((hanh trung) or (manh trung)) tuan nhung cong ((dan toan) OR (manh toan)) cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: hoc chieu sach - ((hanh trung) OR (manh trung)) tuan nhung cong ((dan toan) OR (manh toan)) cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc chieu sach - ((hanh trung) or (manh trung)) tuan nhung cong ((dan toan) OR (manh toan)) cau*".
