Perhaps you should try some spelling variations:
may khoa » da khoa, ly khoa, y khoa
vien cac » vien bach, vien dai, vien da
tu sach » thu sach, su sach, te sach
ve cham » va cham, ve chat, vu cham
xuc van » duc van, luc van, vuc van
minh vi » minh voi, dinh vi, minh va
y mang » cay mang
ve cac » va cac
vi cua » vai cua, di cua
cua tu » cua tuc, cua su, cua cu

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 mang may khoa. hieu ((((ve cac) OR (vien cac))) or (ve cham)) xuc van minh vi cua tu~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach y mang may khoa. hieu ((((ve cac) OR (vien cac))) OR (ve cham)) xuc van minh vi cua tu*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach y mang may khoa. hieu ((((ve cac) OR (vien cac))) or (ve cham)) xuc van minh vi cua tu*".
