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