I agree with you. I didn't build App Store Instant as a replica of Google Instant. With the APIs available, there isn't a reliable way to predict apps.
I built it because iTunes is slow. Try searching iTunes and clicking on an App (to read the description). It takes me 5+ seconds. This takes ~1 second.
