Leaving the search field blank and clicking "Search" should return all books akin to the default behavior.

Describe the bug/problem

Leaving the search field blank and pressing "Search" results in no books from the library being returned. I think it's a better user experience if blank returns all books as that is the default behavior when you first go to the page.

To Reproduce

Steps to reproduce the behavior:

1. Go to 'http://box/books/'
2. Observe that all books in library are shown
3. Click the "Search" button on the upper left of the page
4. See that no books appear.

Expected behavior

Leaving the search field blank and clicking "Search" should return all books akin to the default behavior.

Screenshots

Common corner cases need to not drive teachers crazy: We can debate what that means?

Either way, the behavior needs to be very clear, and very consistent!
