Julio, This is to convert the 1:n and m:n relationships in a DB to multivalued fields in solr. A single sql query ends up giving a 2D matrix where each cell holds one value. It would be harder to denormalize and extract the multivalued fields from a single result set. Check the architecture to see the flow (http://wiki.apache.org/solr/DataImportHandler#arch) --Noble
