Hello, The most promising approach for doing this is BlockJoinQuery. Here is the great intro http://blog.mikemccandless.com/2012/01/searching-relational-content-with.html. This query and lowlevel indexing support is implemented in Lucene. Some work is in progress for Solr https://issues.apache.org/jira/browse/SOLR-3076. The currently present approaches is wiki.apache.org/solr/Join and Grouping aka FieldCollapsing.
