ngang thanh » nang thanh, nganh thanh, nhanh thanh
trung tuan » trung thanh, trung tam, tran tuan
tuan duong » tuyen duong, tuong duong, van duong
duong cong » dung cong, luong cong, duong trong
ngan thanh » nganh thanh, ngon thanh, nhan thanh
hoc thieu » toc thieu, hoc hien
ho chieu » theo chieu, doi chieu, mot chieu

• If you are trying to use Boolean operators, they must be ALL CAPS: ((ho chieu) OR (hoc thieu)) sang - thanh trung tuan duong cong ((ngang thanh) OR (ngan thanh)) cau~.
• Adding a wildcard symbol may retrieve word variants: ((ho chieu) or (hoc thieu)) sang - thanh trung tuan duong cong ((ngang thanh) or (ngan thanh)) cau*.
