• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ((y nang) OR (ky nang)) ma hoi. thien van cau phuc va hanh ((hai hau) or (hat chau)) treo~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ((y nang) OR (ky nang)) ma hoi. thien van cau phuc va hanh ((hai hau) OR (hat chau)) treo.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ((y nang) OR (ky nang)) ma hoi. thien van cau phuc va hanh ((hai hau) or (hat chau)) treo".
