nhan dang » nhan dan, phan dang, tran dang
cua thang » cua hang, cua thanh, xua thang
doi chau » doi chieu, gioi chau, hoi chu
dang cua » dung cua, dong cua, mang cua
long dan » long doan, cong dan, nong dan

• If you are trying to use Boolean operators, they must be ALL CAPS: doi chau tinh - nhan dang cua thang long dan ((toan tai) OR (toan ban))~.
• Adding a wildcard symbol may retrieve word variants: doi chau tinh - nhan dang cua thang long dan ((toan tai) or (toan ban))*.
