The `has_parent` filter accepts a query and a parent type. The query is executed in the parent document space, which is specified by the parent type. This filter return child documents which associated parents have matched. For the rest `has_parent` filter has the same options and works in the same manner as the `has_child` filter.
This is an experimental filter.
Filter example
###################
```
{
"has_parent" : {
"parent_type" : "blog"
"query" : {
"term" : {
"tag" : "something"
}
}
}
}
```
The `parent_type` field name can also be abbreviated to `type`.
Memory considerations
###############
With the current implementation, all _id values are loaded to memory (heap) in order to support fast lookups, so make sure there is enough mem for it.
