steps to reproduce:
firefox or chrome latest version
enter "5520" into the search field adjacent to "series/model" drop down. This drop down should be set to series/model (the default for me).
The search results never populate, but if you enter "Cisco 5520" then it works, but no search results seem to appear for it.
also having that "my saved search" box to the right 100% of the time wastes a ton of space. It would be nice to have that hidden by default..
