• Performing a fuzzy search may retrieve terms with similar spellings: su ((sach ty) OR (sach thu)) hang ca hoi. hieu va cam xuc van anh di ((cua triet) or (va triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su ((sach ty) OR (sach thu)) hang ca hoi. hieu va cam xuc van anh di ((cua triet) OR (va triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "su ((sach ty) OR (sach thu)) hang ca hoi. hieu va cam xuc van anh di ((cua triet) or (va triet))".
