Swish-e
-------

`Siwsh-e <http://swish-e.org/>`_ is a popular indexer, typically used for internal web sites.

This is a search-only adapter, implemented via the SwishE_ Python module (which
doesn't appear to support indexing?). Indexing still has to be performed by
Swish-e itself.

Usage
~~~

::

    swishe://<path>

Installation
~~~~~~~~~~

::

    easy_install SwishE
