For IM there are too many alternatives to count. For search there are a few, DDG is the best known imo, however, none of them is as good as Google's search engine, especially when it comes to Hebrew (my mother tongue). As for Facebook itself, the problem is that it's offering now a combination of social media, photo storage, discussion groups and an IM platform - to name a few. It's not easy to make an alternative to something so complex.
