• Performing a fuzzy search may retrieve terms with similar spellings: ((vu sach) OR (vu bach)) ky tang lai hoi. hieu he nam tu ((va daoh) or (va dao)) dien cau treo~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((vu sach) OR (vu bach)) ky tang lai hoi. hieu he nam tu ((va daoh) OR (va dao)) dien cau treo*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((vu sach) OR (vu bach)) ky tang lai hoi. hieu he nam tu ((va daoh) or (va dao)) dien cau treo*".
