Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
lang van » dang van, tang van, hoang van
thu sach » tu sach, thuat sach, thuoc sach
hieu va » lieu va, hieu qua
va hanh » van hanh, va thanh, ban hanh
va danh » va dinh, va dan, dia danh
lang xa » lang ha, dang xay
lam cua » nam cua, lam chat
va bac » van bac, va cac, va bai

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

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