Thanks for your response Eric. Actually the scenario is to use the Solr search server as a hierarchical storage system also. Where we store objects/files in a hierarchy and do searches on that. something like DB (for files) + Solr. Here I am evaluating Solr with an knowledge management system. So thought of storing in a hierarchy.
