Hi, i agree with Upayavira, probably it's better to create an external app that retrieves content from a db. Anyway, if i am not wrong, finishStage is a method called by the coordinator if you have a distributed search.
if your solr is on a single machine every component should implement only prepare and process methods. HTH.
