• Performing a fuzzy search may retrieve terms with similar spellings: ((tu sach) or (vu sach)) ty lang xa hoi. hieu van nam cuc ((ban banh) OR (ban danh)) di cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (vu sach)) ty lang xa hoi. hieu van nam cuc ((ban banh) OR (ban danh)) di cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) or (vu sach)) ty lang xa hoi. hieu van nam cuc ((ban banh) OR (ban danh)) di cuu tre".
• Adding a wildcard symbol may retrieve word variants: ((tu sach) or (vu sach)) ty lang xa hoi. hieu van nam cuc ((ban banh) OR (ban danh)) di cuu tre*.
