title: Deleting and updating documents in Lucene index
body: <p>Am using <code>Lucene.Net.dll</code>, version 2.0.0.4.</p>
  
  <p>Looks like its <code>IndexWriter</code> class does not have methods for <code>DeleteDocument</code> or <code>UpdateDocument</code>. Am i missing something here? How do I achieve delete, update functionality in this version of Lucene.Net?</p>
  
  <p>Version 2.1 Lucene.dll seems to have support for delete and update documents:</p>
  
  <pre><code>public virtual void DeleteDocuments(Term term);
  public virtual void UpdateDocument(Term term, Document doc);
  </code></pre>
  
  <p>In <a href="https://svn.apache.org/repos/asf/incubator/lucene.net/tags/Lucene.Net_2_1_0/" rel="nofollow noreferrer">here</a> is the source code for verion 2.1, but I will have to download all the files one by one and then build a DLL out of it.</p>
  
  <p>Can I download latest <code>Lucene.dll</code> and Highlighter from some site?</p>
