title: Solr can not process rich documents but already fetched
body: <p>Recently, I am trying to adopt Solr to search rich document files(e.g. .pdf, .doc, xls ...etc)</p>
  
  <p>When I try to import all the files from the disk using Solr admin UI (localhost:18983/solr/#/local.info/dataimport//dataimport), the message always shows "Index Completed" but no document added/updated. </p>

  <p>I have also checked the official online manual to index a directory of rich files(lucene.apache.org/solr/quickstart.html#indexing-a-directory-of-rich-files).</p>
  
  <p>The error messages showed</p>
  
  <pre><code>     SimplePostTool: WARNING: Solr returned an error #400 (Bad Request) for url: localhost:8983/solr/local.info/update/extract?resource.name=%2Fvar%2Fsolr%2Fdata%2Flocal.info%2Frich_documents%2FNEWS.PDF&amp;literal.id=%2Fvar%2Fsolr%2Fdata%2Flocal.info%2Frich_documents%2FNEWS.PDF
