trang cua » tranh cua, tang cua, trung cua
hang cong » dang cong, hang nong, thanh cong
bang cong » dang cong, bang song, dung cong
theo yeu » theo tieu, thiet yeu, theo chu

• If you are trying to use Boolean operators, they must be ALL CAPS: ((theo chieu) OR (theo yeu)) xanh - hanh trang cua ((hang cong) OR (bang cong)) van toan ban~.
• Adding a wildcard symbol may retrieve word variants: ((theo chieu) or (theo yeu)) xanh - hanh trang cua ((hang cong) or (bang cong)) van toan ban*.
