Cross Site Publishing in SharePoint Online

I was asked to test Cross Site Publishing features in SharePoint 2013 Online. I saved the Authoring site collection's (Used Team Site's Template since Product Catalog Template not avialable in SP Online) Pages library as a Catalog. When I connected that catalog in my Publishing site collection, 2 pages created automatically. Category Page is showing the content, but CatelogItem page is empty. How can I configure Content Search Web Part to show the Page Content of the Authoring Sites's page?

Can we show Authoring sites Pages libraries page content on the publishing site?

Is this possible in SharePoint Online Cross Site Publishing?
