• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ty nang ((x hoi) OR (x ho)). thien van cam thuc va ((danh dinh) or (anh dinh)) chau treo~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ty nang ((x hoi) OR (x ho)). thien van cam thuc va ((danh dinh) OR (anh dinh)) chau treo.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ty nang ((x hoi) OR (x ho)). thien van cam thuc va ((danh dinh) or (anh dinh)) chau treo".
• Adding a wildcard symbol may retrieve word variants: tu sach ty nang ((x hoi) OR (x ho)). thien van cam thuc va ((danh dinh) or (anh dinh)) chau treo*.
