• Performing a fuzzy search may retrieve terms with similar spellings: doi chieu sach - nhanh quan ((((luan hung) OR (lan hung))) or (luan chung)) cong tap doan cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: doi chieu sach - nhanh quan ((((luan hung) OR (lan hung))) OR (luan chung)) cong tap doan cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi chieu sach - nhanh quan ((((luan hung) OR (lan hung))) or (luan chung)) cong tap doan cau*".
