If you have subscribed to the service the search page can be found at the top of your regular page.
This search box will search all the metadata you have available for its results. Such as indexes that have Bill numbers, names or other pertinent information. If you have captioning data, this too will be used to provide results.
As you can see here the Search box can be expanded using the + and - buttons to either expand or contract the box.
The expanded box provides more filtering possibilities while the plain keyword search will provide results for all the metadata you have ever generated.
