• Performing a fuzzy search may retrieve terms with similar spellings: te sach ty hang tao hoc. hieu ve cac ((((xuc ban) OR (duc ban))) or (dua ban)) hanh di cua cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ty hang tao hoc. hieu ve cac ((((xuc ban) OR (duc ban))) OR (dua ban)) hanh di cua cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ty hang tao hoc. hieu ve cac ((((xuc ban) OR (duc ban))) or (dua ban)) hanh di cua cau*".
