> With the current version of SOLR and nested indexing, when you are fetch a parent record it returns all the fields of its children. This is increasing the size of data being returned from SOLR and also hits our performance sometime.
> This ticket will be used to update the ChildDocTransformerFactory class with additional parameters to specify the list of fields to be pulled for child documents.
