• Performing a fuzzy search may retrieve terms with similar spellings: te sach doi hang cau hoi. lieu va cam xuc ((va dao) or (va hanh)) vai ((cua triet) OR (cua viet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach doi hang cau hoi. lieu va cam xuc ((va dao) OR (va hanh)) vai ((cua triet) OR (cua viet))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach doi hang cau hoi. lieu va cam xuc ((va dao) or (va hanh)) vai ((cua triet) OR (cua viet))*".
