https://github.com/elastic/elasticsearch-js/issues/2241 notes that there
is no body attribute on a response. This is mostly just a typo in the
example, as `result` itself is a readable stream, unless `meta: true` is
passed, in which case `result.body` will be a readable stream.
Also dropped the callback-style stream processing example as it's a bit
outdated.
