I have created an elastic search cluster (admin/config/elasticsearch-connector/clusters/add). Then in admin/config/search/search_api I have added a demo server and demo index also.
Then I created a page view which shows the "demo index" , I created. I have selected the fields which I want my views to show. Enabled the facets blocks for which the faceted search I wish to achieve.
admin/config/search/search_api/index/demoindex => clicked on Index Now to index all the items and then updated the preview of the view.
The issue I am facing is that, the view I created is blank, it does not show any data but the bundle for which I created the index, do have nodes created in the system.
I have followed the tutorial here :
