Here is an article that shows how to present SharePoint 2010 on a SharePoint 2013 farm: http://nikpatel.net/2012/10/13/understanding-sharepoint-2010-experience-in-sharepoint-2013/
If I do the process of having a SharePoint 2010 on a SharePoint 2013 farm, will I get the search benefits SharePoint 2013 has? Or any of the SharePoint 2013 features?
