I think searching nodes in the Orion platform by serialnumber is an important feature.
In case you want to review the data of a switch/router in Orion without knowing the hostname or the IP address of the device, you can not find the device.
But Orion is able to read and save the serialnumber of network devices (at least Cisco) in the NPM, so the implementation of an additional search filter should not take too much effort, eh?
