Finally, it's time for refactoring our schema and indexing all the downloaded documents.

First of all, we have to rewrite the configurations. In particular, we will define a new Solr core with the name paintings, having the same solrconfig.xml and a slightly modified schema.xml. When we have defined the new Solr core, we have to simply copy the configurations from paintings_start core to a new paintings core, and then we modify the schema.xml file by adding the basic fields we need for our entity.
