Perhaps you should try some spelling variations:
thanh tai » thanh hai, thanh toan, doanh tai
cua triet » cua viet, su triet, va triet
tu sach » thu sach, su sach, te sach
ve cham » va cham, ve chat, vu cham
duc gia » quoc gia
tai cua » thai cua, tai cuc, tri cua
y lang » o lang, tay lang, yen lang
_ lang » o lang, _ land
ve cam » ve cac, va cam, ve cai

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

• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ((y lang) or (_ lang)) xa hoi. hieu ((ve cam) OR (ve cham)) duc gia thanh tai cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ((y lang) OR (_ lang)) xa hoi. hieu ((ve cam) OR (ve cham)) duc gia thanh tai cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ((y lang) or (_ lang)) xa hoi. hieu ((ve cam) OR (ve cham)) duc gia thanh tai cua triet".
• Adding a wildcard symbol may retrieve word variants: tu sach ((y lang) or (_ lang)) xa hoi. hieu ((ve cam) OR (ve cham)) duc gia thanh tai cua triet*.
