• Performing a fuzzy search may retrieve terms with similar spellings: (( tu sach nha hoa ((giao bay) OR (gia ba)) khong hinh ) or ( tu sach xa me nguoi benh hong hinh ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( tu sach nha hoa ((giao bay) OR (gia ba)) khong hinh ) OR ( tu sach xa me nguoi benh hong hinh )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( tu sach nha hoa ((giao bay) OR (gia ba)) khong hinh ) or ( tu sach xa me nguoi benh hong hinh ))".
• Adding a wildcard symbol may retrieve word variants: (( tu sach nha hoa ((giao bay) OR (gia ba)) khong hinh ) or ( tu sach xa me nguoi benh hong hinh ))*.
