I am publishing SharePoint 2013 Service Applications Managed Metadata Service and Search Service Application to SharePoint 2010 farm. I have followed TechNet and able to successfully publish the service applications. My SharePoint 2013 is publishing farm and SharePoint 2010 is consuming farm.
Problem: I want to use both of the service applications at the same time in consuming farm's web application. I need to show search results from both service applications at the same time. Currently only the Default service application proxy is showing result.
If i set SharePoint 2013 search service proxy as Default in Service Connections, it shows result from SharePoint 2013 only. If i set Managed Metadata Service proxy of SharePoint 2013 as default, it displays results from SharePoint 2013 only.
How can i use service applications of both farms at the same time?
Update 1 (14-02-2017): I have just confirmed, i am able to see both SharePoint 2013 and SharePoint 2010 Managed Metadata Service applications in SharePoint 2010. However, still looking for Search Service Application results in SharePoint 2010.
