Solr 5.2 child documents

[Novin]

Hi,

When I query q=*:* I can't get child documents back, Below is 
configuration I am using for child Document to index in solr.

Am I missing something?

note: child document are using dynamic fields.



SolrInputDocument childDoc = new SolrInputDocument();
childDoc.addfield("index_l", 20000);
childDoc.addfield("datetime_dt", DateTime.now().toIsoDateTime());

parentDoc. .addChildDocument(childDoc);

schema.xml
<field name="_root_" type="string" indexed="true" stored="true"/>

solrconfig.xml
<cache name="perSegFilter"
      class="solr.search.LRUCache"
      size="10"
      initialSize="0"
      autowarmCount="10" />

If needed more info I can provide that either.

Cheeers,
Novin
