You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: so sach ((ky lang) OR (ky tang)) xa hoi. hieu qua cam xuc ((va hanh) or (va danh)) lai cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: so sach ((ky lang) OR (ky tang)) xa hoi. hieu qua cam xuc ((va hanh) OR (va danh)) lai cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so sach ((ky lang) OR (ky tang)) xa hoi. hieu qua cam xuc ((va hanh) or (va danh)) lai cua triet".
• Adding a wildcard symbol may retrieve word variants: so sach ((ky lang) OR (ky tang)) xa hoi. hieu qua cam xuc ((va hanh) or (va danh)) lai cua triet*.
