• Performing a fuzzy search may retrieve terms with similar spellings: theo ((chieu sach) or (tieu danh)) - thanh quang ((huy dung) OR (huy duong)) cong ban than cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((chieu sach) OR (tieu danh)) - thanh quang ((huy dung) OR (huy duong)) cong ban than cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chieu sach) or (tieu danh)) - thanh quang ((huy dung) OR (huy duong)) cong ban than cau*".
