Very noted - as has been discussed a few times, the search feature as it exists now is very specific to a database of less than 200 books. What would be a worse search feature at this point would just be a search bar that let you randomly search for titles until you happened to find one we have in the test database.
The search design - and the site design in general - will be revamped to included much more in depth filters and more traditional searching ability as we gain more books in the database. As we gain books, we'll switch away from being a technology demonstration and towards an actual service, which means we'll move the GUI forward in the site, improve the user interface, and let people do all the things they want to do.
