• Performing a fuzzy search may retrieve terms with similar spellings: tu sach thu thang ma hoi. lieu ((va dai) OR (va dao)) truc ((va hanh) or (tuan anh)) va cau treo~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach thu thang ma hoi. lieu ((va dai) OR (va dao)) truc ((va hanh) OR (tuan anh)) va cau treo.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach thu thang ma hoi. lieu ((va dai) OR (va dao)) truc ((va hanh) or (tuan anh)) va cau treo".
