Perhaps you should try some spelling variations:
nganh hang » nhanh thang, nganh thanh, nganh khong
dau tren » dau tien, dat tren, dau tieng
su sach » so sach, vu sach
ty nang » ty xang, ty hang, ly nang
hieu ve » hieu va, hieu van
cam luc » cam xuc, cau luc
ve cam » ve cham, ve cac, va cam
vi dau » vi dai, va dau, bi dau

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

• Performing a fuzzy search may retrieve terms with similar spellings: su sach ((ty nang) or (ky nang)) xa hoi. hieu ve cam luc ((nganh hang) OR (ngan hang)) vi dau tren~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ((ty nang) OR (ky nang)) xa hoi. hieu ve cam luc ((nganh hang) OR (ngan hang)) vi dau tren.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ((ty nang) or (ky nang)) xa hoi. hieu ve cam luc ((nganh hang) OR (ngan hang)) vi dau tren".
• Adding a wildcard symbol may retrieve word variants: su sach ((ty nang) or (ky nang)) xa hoi. hieu ve cam luc ((nganh hang) OR (ngan hang)) vi dau tren*.
