• Performing a fuzzy search may retrieve terms with similar spellings: su sach ky sang lap hai. hieu ve ((cam luc) or (cam xuc)) ((va doan) OR (van doan)) vi cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ky sang lap hai. hieu ve ((cam luc) OR (cam xuc)) ((va doan) OR (van doan)) vi cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ky sang lap hai. hieu ve ((cam luc) or (cam xuc)) ((va doan) OR (van doan)) vi cua te".
• Adding a wildcard symbol may retrieve word variants: su sach ky sang lap hai. hieu ve ((cam luc) or (cam xuc)) ((va doan) OR (van doan)) vi cua te*.
