• Performing a fuzzy search may retrieve terms with similar spellings: su sach ly nang ((tai hoi) or (dai hoi)). hieu ((van cam) OR (van nam)) tuc va danh hai cau treo~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ly nang ((tai hoi) OR (dai hoi)). hieu ((van cam) OR (van nam)) tuc va danh hai cau treo*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ly nang ((tai hoi) or (dai hoi)). hieu ((van cam) OR (van nam)) tuc va danh hai cau treo*".
