URL device search not working properly

I have successfully integrated Zenoss 4.5.2 into a web application that has a link for for looking up a specific device via URL. For example, in order to show device in Zenoss the URL would be:

http://:8080/zport/searchDevicesqueryString=foo

This works perfectly unless there are more devices in Zenoss who's names start with "foo". In this case Zenoss displays a list of matching device names instead of device "foo":

[, ]

It seems there is no way of telling Zenoss via URL to look up device "foo" if there are other devices starting with "foo" in their name, or do I miss something
