• Performing a fuzzy search may retrieve terms with similar spellings: (( tu sach nha ((ve giai) OR (va giai)) cong hong minh ) or ( te sach cha me gioi cong hoa minh ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( tu sach nha ((ve giai) OR (va giai)) cong hong minh ) OR ( te sach cha me gioi cong hoa minh )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( tu sach nha ((ve giai) OR (va giai)) cong hong minh ) or ( te sach cha me gioi cong hoa minh ))".
• Adding a wildcard symbol may retrieve word variants: (( tu sach nha ((ve giai) OR (va giai)) cong hong minh ) or ( te sach cha me gioi cong hoa minh ))*.
