• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu xanh - hanh ((trinh luan) OR (trinh quan)) phan tong dan ((thanh chau) OR (toan cao))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu xanh - hanh ((trinh luan) OR (trinh quan)) phan tong dan ((thanh chau) or (toan cao))*".
