title: NeedIndexError on upload
body: <p>I am currently developing a project which makes use of google app engine. Running the application on my development server using *dev_app_server.py* works perfectly for me, but as soon as I upload the application online I get the following error:</p>
  
  <pre><code>NeedIndexError: no matching index found.
  The suggested index for this query is:
  - kind: Comment
    properties:
    - name: parent
    - name: date_created
      direction: desc
  </code></pre>
  
  <p>At first I thought it was because the Indexes still needed to be built as suggested by <a href="https://developers.google.com/appengine/docs/python/gettingstartedpython27/uploading" rel="nofollow">this page</a> - but it has been days since I first uploaded the application and first got this error. Could anyone given an idea of what could be wrong or what I should look out for to solve this error?</p>
  
  <p>For more details about the error you can access the page directly and see what I mean:

  <p><strong>EDIT</strong>
  I put my index.yaml in a gist so that you can all take a look at it if it helps:</p>
