hang luong » nang luong, hang thuong, hoang vuong
hoc thieu » toc thieu, hoc hien
trung cap » truong cao, trung tam
luong tai » dung tai, luong va
cap hang » cap hoang, cap bang, cap han

• If you are trying to use Boolean operators, they must be ALL CAPS: ((hoc thieu) OR (theo chieu)) xanh - thanh trung cap hang luong tai toan tap~.
• Adding a wildcard symbol may retrieve word variants: ((hoc thieu) or (theo chieu)) xanh - thanh trung cap hang luong tai toan tap*.
