# Parent Inner Hits
> More info about inner hits is in the [official elasticsearch docs][1]
The `parent/child` inner_hits can be used to include parent or child.
The usage of parent inner hits is very similar to that of nested [inner hits](Nested.md), the only
difference is that in stead of passing the `path` to the nested object, the parent/child `type`
needs to be passed to the `$path` variable.
## Simple example
```JSON
{
"inner_hits" : {
"children" : {
"type" : {
"article" : {
"query" : {
"match" : {"title" : "[actual query]"}
}
}
}
}
}
}
```
And now the query via DSL:
```php
$matchQuery = new MatchQuery('title', '[actual query]');
$innerHit = new ParentInnerHit('children', 'article', $matchQuery);
$search = new Search();
$search->addInnerHit($innerHit);
$search->toArray();
```
