• If you are trying to use Boolean operators, they must be ALL CAPS: doi chieu xanh - ((danh trung) OR (tdanh trung)) cua phuong ((trong ban) OR (trong bang)) toan cau~.
• Adding a wildcard symbol may retrieve word variants: doi chieu xanh - ((danh trung) or (tdanh trung)) cua phuong ((trong ban) or (trong bang)) toan cau*.
