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