Okay, i think this one might work for the moment: https://gist.github.com/nickvergessen/c02fa7e62b8af5e707c5
But I'm not sure, I didnt set up sphinx yet, and it requires some changes to the sphinx config, but I dont know whether this is possible this way, or whether the search index needs to be rebuild or what so ever. I will try to poke @naderman for some help
