• Performing a fuzzy search may retrieve terms with similar spellings: (((( su ((cach kinh) or (cac tinh)) de gia cuong ) or ( ((tu sach) or (te sach)) danh co giac cong ))) or ((( tu ((sac tinh) or (may tinh)) doi gia luong ) or ( tu hat ((tinh doi) OR (tinh hoc)) gia long ))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((( su ((cach kinh) OR (cac tinh)) de gia cuong ) OR ( ((tu sach) OR (te sach)) danh co giac cong ))) OR ((( tu ((sac tinh) OR (may tinh)) doi gia luong ) OR ( tu hat ((tinh doi) OR (tinh hoc)) gia long ))))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((( su ((cach kinh) or (cac tinh)) de gia cuong ) or ( ((tu sach) or (te sach)) danh co giac cong ))) or ((( tu ((sac tinh) or (may tinh)) doi gia luong ) or ( tu hat ((tinh doi) OR (tinh hoc)) gia long ))))*".
