nested vs object in Elasticsearch

Question

Can someone explain what is a difference between "object" and "nested" fields in documents in Elasticsearch?

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.

Documentation for object: http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/mapping-object-type.html Documentation for nestes:http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/mapping-nested-type.html

but I still cant understand a difference...

Answer 1

What your are calling "object" is probably "inner object" in elasticsearch.

Answer 2

The question is asked long ago. Just to refresh the answer, here is the link to the latest documentation. It describes pretty well the difference how internally Elastic stores documents and find matches for queries
