Hello All,
In 6.4 (Solr-9717)  SortingResponseWriter is renamed to ExportWriter and moved to a different package.
For migrating to higher Solr (post 6.4) versions, I  need to help with compatible functionalities.

Application is using  SortingResponseWriter in the searcher handlers inform method to register responseWriters for the xSort.
Since the class and write methods Signature   is changed, what are alternative ways to use the functionality.

 ThanksRavi
