Btw, we've just released a tutorial helping you to implement the same search experience: http://www.algolia.com/doc/tutorials/instant-search
(source code is on github: https://github.com/algolia/instant-search-demo)
A couple of weeks to change out search completely, get full faceting as well as additional indexes to support everything in Arabic.
I continue to be blown away by Algolia and it's potential.
