Hi,

## I'm trying to understand the difference and limitation of these "multi field" core types:

## Array: [http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/mapping-array-type.html](http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/mapping-array-type.html)

## Nested: [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)

Object: [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)

So far I found this  
article [http://obtao.com/blog/2014/04/elasticsearch-advanced-search-and-nested-objects/](http://obtao.com/blog/2014/04/elasticsearch-advanced-search-and-nested-objects/)

Do you have other advices, presentations or resources to know when you'd  
better use each type?

Thanks,  
Eric
