title: Azure Library for Lucene.Net - FileNotFound Exception
body: <p>I'm working with the Azure Library for Lucene.Net but I am running into FileNotFound Exceptions when I try to append to the index.</p>
  
  <p>Everything works great with the FSDirectory.  I have a ton of unit tests working great against the RAMDirectory.</p>
  
  <p><strong>Here is the infrastructure:</strong></p>
  
  <ol>
  <li>Single Role maintains Index Writer Singleton.</li>
  <li>Separate web service maintains a single instance of the Searcher that points to the same index in read-only mode.</li>
  <li>When a change events occur the Index Writer Role picks up the change, modifies the index, and commits.</li>
  <li>After a certain period of time the Searcher recycles to pick up the latest index changes.</li>
  </ol>
  
  <p><strong>Exceptions:</strong> Upon the change, and from then on, I get a FileNotFound exception from the AzureDirectory.  The file reported as not found changes but one example is "_h.cfs."  When the searcher recycles and attempts to reload the index I get FileNotFound exceptions on the searcher as well...</p>
  
  <p><strong>Couple Other Important Points:</strong>
   1. Initial creation of the full index works fine.
   2. Searching against the initially created index works fine.
   3. I'm using Lucene .Net V. 2.9.2</p>
  
  <p>Any thoughts or suggestions?  This is unfortunately the last issue I need to resolve before releasing the project...</p>
  
  <p>Thanks,
  Tim</p>
