• If you are trying to use Boolean operators, they must be ALL CAPS: hoc hien xanh - ((thanh trung) OR (thanh tung)) tuan nhung cong tan ((tran tuan) OR (tran quang))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc hien xanh - ((thanh trung) OR (thanh tung)) tuan nhung cong tan ((tran tuan) or (tran quang))*".
