I'm working with SharePoint online and have the requirement to aggregate content from subsites into a top level site. When I go to add the content search web part it is not available in the web part gallery.
I've just created a brand new team site and the content search web part is available in there and I've gone through all the features that are activated at both site collection and site level and they are the same in the new site as they are in the existing site.
Can anyone tell me how I can get a content search web part in my existing site. I really don't want to have to migrate over to a new site.
