i must admit that i have no clue about the sphinx index feature. trying to figure out what is going on i mainly notice that we seem to get mixed up with the normal symfony doc index and seem to be not overly consistent with how we index things (e.g. only half of the bundles show up near CmfContentBundle http://symfony.com/doc/master/genindex.html)

should i remove the "single:" prefix and just leave the name where to add this in the index?
and should we actually prefix all our index entries into some sort of cmf subspace?
