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