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