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