• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((thieu xanh) OR (chinh sach)) - thanh tran quang nhung cong ngang ((tuan tap) OR (tuyen tap))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((thieu xanh) or (chinh sach)) - thanh tran quang nhung cong ngang ((tuan tap) OR (tuyen tap))~".
• Adding a wildcard symbol may retrieve word variants: hoc ((thieu xanh) or (chinh sach)) - thanh tran quang nhung cong ngang ((tuan tap) OR (tuyen tap))*.
