| /** This class overrides and somewhat changes the behavior of the |

| * the right information to Tika. When SolrJ uses GET or POST but not |
| * multipart-post, it does not include multipart headers that Tika uses - |
| * specifically, the name of the document and the length of the document. |
| * Patches have been submitted to the SOLR ticket queue to address this |
| * problem in a method-insensitive way, but so far there has been no sign that |
| * the Solr team is interested in committing them. |
