title: Doesn't index or extract the Document (.pdf .doc) from Remotely
body: <p>I am using Solr 3.1, Apache Tika 0.9 and Solrnet 0.3.1 to index the
  docuent like a .doc and .pdf file.</p>
  
  <p>I have successfully index and extract document on locally using this
  code</p>
  
  <pre><code>Startup.Init&lt;Article&gt;("http://k9server:8080/solr");
          ISolrOperations&lt;Article&gt; solr = ServiceLocator.Current.GetInstance &lt;ISolrOperations&lt;Article&gt;&gt;();
          string filecontent = null;
          using(var file = File.OpenRead(@"D:\\solr.doc")){
                      var response = solr.Extract(new ExtractParameters(file, "abcd1") {
                          ExtractOnly  = true,
                          ExtractFormat = ExtractFormat.Text,
              });
              filecontent = response.Content;
          }
          solr.Add(new Article() {
                  ID  = "36",
                  EMAIL = "1234",
                  COMMENTS = filecontent,
                  PRO_ID = 256
          });
          // commit to the index
          solr.Commit();
