Hello,

I'm quite a newbie in ES world so please forgive me if I write something  
stupid.

I have data organized in a hierarchical way:  
.  
`-- [id=1 title="build a car" release="1.0"]`-- [id=2 title="find the wheels"]

When users look for "1.0" and "wheels" the should get document n°2  
I tried to use the "parent" relationship (when I create document n°2, I  
tell ES that document 1 is it's parent) but I get no results when I  
querying like  
{  
"query": {  
"bool": {  
"must": [  
{  
"term": {  
"release": "1.0"  
}  
},  
{  
"term": {  
"title": "wheels"  
}  
}  
]  
}  
}  
}

How can I solve my problem ?

Thanks,  
Manuel

I think that nested docs fits better to your use case. See:  
[Elasticsearch Platform — Find real-time answers at scale | Elastic](http://www.elasticsearch.org/guide/reference/mapping/nested-type.html)  
[http://www.elasticsearch.org/guide/reference/mapping/nested-type.html](http://www.elasticsearch.org/guide/reference/mapping/nested-type.html)

Have a look also at  
[Elasticsearch Platform — Find real-time answers at scale | Elastic](http://www.elasticsearch.org/guide/reference/query-dsl/has-child-query.html)  
[http://www.elasticsearch.org/guide/reference/query-dsl/has-child-query.html](http://www.elasticsearch.org/guide/reference/query-dsl/has-child-query.html)  
and  
[Elasticsearch Platform — Find real-time answers at scale | Elastic](http://www.elasticsearch.org/guide/reference/query-dsl/has-parent-query.html)  
[http://www.elasticsearch.org/guide/reference/query-dsl/has-parent-query.html](http://www.elasticsearch.org/guide/reference/query-dsl/has-parent-query.html)

I think (not sure) it can help here.

My 2 cents

David.
