iMessage search not working as expected on iPhone

With the latest update to the phone lots of cosmetic changes occurred. The search function in iMessage is not working the way it used to. When I enter a name it comes up with text messages that have the name mentioned and not the group or message with the person the way it used to. It is making it very difficult to search for previous messages. Is there a way to revert it back to the old way? Or is there a setting I do not have correct that I could change?
