If the data is from another Solr instance, consider the [subquery] Document Transformer here: https://cwiki.apache.org/confluence/display/solr/Transforming+Result+Documents#TransformingResultDocuments-[subquery]
More broadly, you can write a custom DocTransformer plugin do insert anything you want in the output documents. NOTE: DocTransformer only works on the top N docs being returned, which is what I think you want. IOW, if rows=10 it only "sees" 10 documents even if numFound is millions.
