Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
so sach » so sanh, co sach, hoc sach
bo sach » co sach, hoc sach
lang xa » lang ha, dang xay, lang van
qua cam » qua cham, qua cac, qua ca
y lang » o lang, _ lang, tay lang
xuc va » tuc va, luc va, xac va
vi cua » vai cua, di cua

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

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