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