HI David,
I am sorry but currently we do not have the timeframe when this content search will be available in EasySocial.
Currently the EasySocial actually search on users, your photos and your friend list. These are the core items that builtin in EasySocial search. Anyway, We've added search indexer integration into EasyBlog latest version so that when user craeted new blog posts, EasyBlog will add into EasySocial indexer and user will be able to search them in EasySocial search
As for the others content, we will be adding from time to time and if you've any specific request, you can submit your request at our user voice page
