• Performing a fuzzy search may retrieve terms with similar spellings: vu sach thue lang ((ha hoi) OR (ha noi)). hieu ((van cam) or (van nam)) luc va hanh va cau treo~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu sach thue lang ((ha hoi) OR (ha noi)). hieu ((van cam) OR (van nam)) luc va hanh va cau treo.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sach thue lang ((ha hoi) OR (ha noi)). hieu ((van cam) or (van nam)) luc va hanh va cau treo".
