-### Reindex
-
-Copy documents from one index and cluster into another one, for example for purposes of changing
-the settings and mappings of the index.
-
-**NOTE:** Elasticsearch natively supports re-indexing since version 2.3. This extension is useful
-          when you need the feature on older versions.
-
-When the extension is loaded together with the
-[Ruby client for Elasticsearch](../elasticsearch/README.md),
-a `reindex` method is added to the client:
-
-    require 'elasticsearch'
-    require 'elasticsearch/extensions/reindex'
-
-    client = Elasticsearch::Client.new
-    target_client = Elasticsearch::Client.new url: 'http://localhost:9250', log: true
-
-    client.index index: 'test', type: 'd', body: { title: 'foo' }
-
-    client.reindex source: { index: 'test' },
-                   target: { index: 'test', client: target_client },
-                   transform: lambda { |doc| doc['_source']['title'].upcase! },
-                   refresh: true
-    # => { errors: 0 }
-
-    target_client.search index: 'test'
-    # => ... hits ... "title"=>"FOO"
-
-The method takes similar arguments as the core API
-[`reindex`](http://www.rubydoc.info/gems/elasticsearch-api/Elasticsearch/API/Actions#reindex-instance_method)
-method.
-
-You can also use the `Reindex` class directly:
-
-    require 'elasticsearch'
-    require 'elasticsearch/extensions/reindex'
-
-    client = Elasticsearch::Client.new
-
-    reindex = Elasticsearch::Extensions::Reindex.new \
-                source: { index: 'test', client: client },
-                target: { index: 'test-copy' }
-
-    reindex.perform
-
-See more information in the [`Elasticsearch::Extensions::Reindex::Reindex`](lib/elasticsearch/extensions/reindex.rb)
-class documentation.
