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