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