Perhaps you should try some spelling variations:
thuat san » thuat toan, thuat song, thuat lanh
thanh hai » thanh phan, thanh hoa, thanh san
thanh lai » thanh lap, thanh loi, thanh tai
chau tre » chay tren, chau tho, cho tre
hieu va » lieu va, hieu qua
lang xa » lang ha, dang xay, lang van
dao xuc » dao duc, dao tuc, dao xu
va dao » ca dao
xuc va » duc va, tuc va, luc va
san y » dan y, san _

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 ((lang xa) or (van xay)) hoi. hieu va dao xuc va ((thanh lai) OR (thanh hai)) chau tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thuat san y ((lang xa) OR (van xay)) hoi. hieu va dao xuc va ((thanh lai) OR (thanh hai)) chau tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuat san y ((lang xa) or (van xay)) hoi. hieu va dao xuc va ((thanh lai) OR (thanh hai)) chau tre*".
