Simple Django example project using xappy search.

Before you start, run

    $ ./scripts/update_index.py --full

once to create the intial index.

You can then edit objects using the admin interface and run the script
again to have your changes applied to the index.

Interesting places to look at:

    * scripts/update_index.py
    * search/models.py (index definition)
    * main/views.py (doing the search)
    * main/templates/search.html (display of the search results)
