• If you are trying to use Boolean operators, they must be ALL CAPS: doc hieu xanh - ((((hoach mang) OR (nhoach mang))) OR (hanh trang)) xuan thuong luong tin van ban~.
• Adding a wildcard symbol may retrieve word variants: doc hieu xanh - ((((hoach mang) or (nhoach mang))) or (hanh trang)) xuan thuong luong tin van ban*.
