title: Django Haystack Rebuild Index
body: <p>I was reading the 'Getting Started' guide of Haystack and tried to implement Whoosh backend for my website with Haystack. I was successful in setting up the whole project and I can also see the search box on my search.html template. I am unable to build the index though. </p>
  
  <p>When I type ./manage.py rebuild_index, I get the error:</p>
  
  <p><strong>Unknown command: rebuild_index</strong></p>
  
  <p>I know this is a trivial issue. I am unable to understand how the manage.py file can ever understand commands that were not originally a part of it. </p>
