• Performing a fuzzy search may retrieve terms with similar spellings: te sach ly hang ((mai hoi) OR (mai khoi)). hieu vien dai xuc van minh ((vai cau) or (van cau)) tren~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ly hang ((mai hoi) OR (mai khoi)). hieu vien dai xuc van minh ((vai cau) OR (van cau)) tren.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ly hang ((mai hoi) OR (mai khoi)). hieu vien dai xuc van minh ((vai cau) or (van cau)) tren".
• Adding a wildcard symbol may retrieve word variants: te sach ly hang ((mai hoi) OR (mai khoi)). hieu vien dai xuc van minh ((vai cau) or (van cau)) tren*.
