Perhaps you should try some spelling variations:
ban thanh » ban hanh, ban hang
cua triet » cua viet, su triet, va triet
thu sach » tu sach, thuat sach, thuoc sach
va thanh » gia thanh, va tinh, le thanh
ty nang » ky nang, ty hang, ly nang
cac dai » cac dan, cac bai, can dai
lam cua » nam cua, lam chat

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 ((ty nang) or (ty xang)) xa hoi. lieu va cac dai ((va thanh) OR (ban thanh)) lam cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach ((ty nang) OR (ty xang)) xa hoi. lieu va cac dai ((va thanh) OR (ban thanh)) lam cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach ((ty nang) or (ty xang)) xa hoi. lieu va cac dai ((va thanh) OR (ban thanh)) lam cua triet".
• Adding a wildcard symbol may retrieve word variants: thu sach ((ty nang) or (ty xang)) xa hoi. lieu va cac dai ((va thanh) OR (ban thanh)) lam cua triet*.
