I'm trying out Result Sources at the Search Service Application level (i.e. within Central Admin). When I create a new source I can click the link to Launch Query Builder, but the Search Result Preview panel gives the following error:
The Search display templates are not present on this site collection. To add them, you need to activate the "Search Server Web Parts and Templates" feature on the Site Collection Features page. Correlation ID: 94b6249c-d255-602d-b77b-757efe4b3071 Display Error: The display template had an error. You can correct it by fixing the template or by changing the display template used in either the Web Part properties or Result Types. Template '~sitecollection/_catalogs/masterpage/Display Templates/System/Control_QueryBuilderPreview.js' not found or has syntax errors. (LoadTemplate: )
This is Central Admin, and when I go to Site Settings, there is no "Site Collection Features " link, and in the "Site Features" there is no "Search Server Web Parts and Templates" feature.
Any ideas how I can get the query builder working again?
