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