+phorkie makes use of an Elasticsearch__ installation if you have one.
+
+It is used to provide search capabilities and the list of recent pastes.
+
+__ http://www.elasticsearch.org/
+
+Setup
+=====
+Edit ``config.php``, setting the ``elasticsearch`` property to the HTTP URL
+of the index, e.g. ::
+
+ http://localhost:9200/phorkie/
+
+Run the index script to import all existing pastes into the index::
+
+ php scripts/index.php
+
+That's all. Open phorkie in your browser, and you'll notice the search box
+in the top menu.
