• Performing a fuzzy search may retrieve terms with similar spellings: thuoc sach ty ((xang xa) OR (lang xa)) hoi. hieu ve ((cau phuc) or (chau phu)) vu hanh va cau treo~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thuoc sach ty ((xang xa) OR (lang xa)) hoi. hieu ve ((cau phuc) OR (chau phu)) vu hanh va cau treo*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuoc sach ty ((xang xa) OR (lang xa)) hoi. hieu ve ((cau phuc) or (chau phu)) vu hanh va cau treo*".
