While using the iOS app I have noticed how little I use the search feature since it is buried in its own menu away from the library on the iOS UI. Apple has integrated search throughout many of its apps quite nicely. I particularly like how it hides away in the latest Music app, and can be "pulled down" by the user when one needs it (see screenshots below). This functions as a neat way to save screen real estate, and makes things pretty. For those with larger collections this may be a enjoyed feature for YACReader. Just a thought.
