chieu sach » chinh sach, chiet tach, chieu sang
nhung bong » nhung cong, nhung bang, nhung chong
tran cong » tran hong, trien cong, tran hoang

• If you are trying to use Boolean operators, they must be ALL CAPS: theo chieu sach - tran cong cua ((nhung bong) OR (nhung phong)) van thanh cau~.
• Adding a wildcard symbol may retrieve word variants: theo chieu sach - tran cong cua ((nhung bong) or (nhung phong)) van thanh cau*.
