Hi, in SharePoint 2013 I have used a Search results web part to find newsfeeds. I have managed to do this okay but trying to sort the result in date order has been a real problem not matter what managed property I use. It can be descending or ascending and it does not make a blind bit of difference, as the result stays the same. I also notice that you get the same problem if you go on the Conversation search results page, trying to sort it by created or another managed property.
Thanks for the reply. I copied the conversations result source file and sorted from there, and that seems to have done the trick.
