It doesn't look like a general resource issue as it works fine for me

What happens if you try searching in a Books Search panel (as opposed to using the Inline Search) as per the example on the right of my screenshot?

If you try it and it doesn't work, please post a screenshot 

It is possible that it needs to be reindexed, or that there is some parameter that is causing the search to fail.
