Perhaps you should try some spelling variations:
thuat san » thuat toan, thuat song, thuat lanh
nhan dien » nhan vien, nhan dieu, nhan dan
cam hoc » cao hoc, am hoc, cam hoa
ly nang » ky nang, ly hang, ly vang
hang di » hang doi, hang vi, hang dien
hieu ve » hieu va, hieu van
ve cam » ve cham, ve cac, va cam
y nang » ky nang, v nang, may nang
x hoi » xa hoi, o hoi, x ho

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

• Performing a fuzzy search may retrieve terms with similar spellings: thuat san ((y nang) OR (ly nang)) x hoi. hieu ve cam hoc va ((hang di) or (nhan dien)) qua su~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thuat san ((y nang) OR (ly nang)) x hoi. hieu ve cam hoc va ((hang di) OR (nhan dien)) qua su.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuat san ((y nang) OR (ly nang)) x hoi. hieu ve cam hoc va ((hang di) or (nhan dien)) qua su".
• Adding a wildcard symbol may retrieve word variants: thuat san ((y nang) OR (ly nang)) x hoi. hieu ve cam hoc va ((hang di) or (nhan dien)) qua su*.
