How to get search results sorted by language in solr? We have used Apache solr multilingual module for language specific search.
But we want the other language results to be shown below the current language search result.
How we can achieve it using solr?

Is there any module needed or any custom coding require?

Below is the example for displaying search results :- 


  If I am currently using site in german and searched for any content
  then german results needs to be appear first and then other language
  content.
You could build your search with the apachesolr_views module (https://www.drupal.org/project/apachesolr_views), allow all languages and then group by language in the view.
