• Performing a fuzzy search may retrieve terms with similar spellings: su sach v nang ma hoi. thien van lam ((duc va) or (truc va)) danh hai ((hau treo) OR (cau theo))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach v nang ma hoi. thien van lam ((duc va) OR (truc va)) danh hai ((hau treo) OR (cau theo))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach v nang ma hoi. thien van lam ((duc va) or (truc va)) danh hai ((hau treo) OR (cau theo))*".
