I don't think the new join package in Lucene 3.4 will work for this case; you need more general join implementation, which eg Solr and ElasticSearch have implemented.
Generic join hasn't yet been factored out into Lucene (but I think it really needs to be... any volunteers!?). Lucene's join package can handle use cases like nested documents or parent/child, because it requires that you index a single primary row AND all joined documents together as a single block of documents.
