• Performing a fuzzy search may retrieve terms with similar spellings: (( so sach cha me gioi binh ((dong tin) OR (luong tin)) ) or ( tu sach cha me gioi co phong tin ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( so sach cha me gioi binh ((dong tin) OR (luong tin)) ) OR ( tu sach cha me gioi co phong tin ))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( so sach cha me gioi binh ((dong tin) OR (luong tin)) ) or ( tu sach cha me gioi co phong tin ))*".
