+Elasticsearch-DSL
+-----------------
+
+For a more high level client library with more limited scope, have a look at
+`elasticsearch-dsl`_ - a more pythonic library sitting on top of
+``elasticsearch-py``.
+
+`elasticsearch-dsl`_ provides a more convenient and idiomatic way to write and manipulate
+`queries`_ by mirroring the terminology and structure of Elasticsearch JSON DSL
+while exposing the whole range of the DSL from Python
+either directly using defined classes or a queryset-like expressions.
+
+It also provides an optional `persistence layer`_ for working with documents as
+Python objects in an ORM-like fashion: defining mappings, retrieving and saving
+documents, wrapping the document data in user-defined classes.
