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