title: nested vs object in Elasticsearch
body: <p>Can someone explain what is a difference between "object" and "nested" fields in documents in Elasticsearch? </p>
  
  <p>I know by default field is defined as object. I also know that I can access object field with a dot like this: my_field.name, my_field.title etc.</p>
  
  <p>Documentation for object: <a href="http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/mapping-object-type.html">http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/mapping-object-type.html</a>
  Documentation for nestes:<a href="http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/mapping-nested-type.html">http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/mapping-nested-type.html</a></p>
  
  <p>but I still cant understand a difference...</p>
