hanh tang » hanh trang, anh tang, hanh mang
hang cong » dang cong, hang nong, bang cong
tang cua » mang cua, hang cua, tang luan

• If you are trying to use Boolean operators, they must be ALL CAPS: hoc thieu ngan - hanh tang cua hang cong ((van tuan) OR (van quan)) ban~.
• Adding a wildcard symbol may retrieve word variants: hoc thieu ngan - hanh tang cua hang cong ((van tuan) or (van quan)) ban*.
