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