truong cua » truong ca, truong quan, truong cao
thong cong » trong cong, tong cong, thong thong
trung cap » truong cao, trung tam
cong bang » cuong bang, dong bang, hong bang
bang nhan » ban nhan, hoang nhan, bang thanh
ho chieu » theo chieu, hoc thieu, doi chieu
nhan cap » khan cap, than cap, nhan cach

• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu sach - thanh ((trung cap) OR (truong cua)) thong cong bang nhan cap~.
• Adding a wildcard symbol may retrieve word variants: ho chieu sach - thanh ((trung cap) or (truong cua)) thong cong bang nhan cap*.
