    Loads a backend for interacting with the search engine.

    Requires a ``backend_path``. It should be a string resembling a Python
    import path, pointing to a ``BaseEngine`` subclass. The built-in options
    available include::

      * haystack.backends.solr.SolrEngine
      * haystack.backends.xapian.XapianEngine (third-party)
      * haystack.backends.whoosh.WhooshEngine
      * haystack.backends.simple.SimpleEngine

    If you've implemented a custom backend, you can provide the path to
    your backend & matching ``Engine`` class. For example::

      ``myapp.search_backends.CustomSolrEngine``
