==== Has Parent Query

See {ref}/query-dsl-has-parent-query.html[Has Parent]

When using the `has_parent` query it is important to use the `PreBuiltTransportClient` instead of the regular client:

[source,java]
--------------------------------------------------
Settings settings = Settings.builder().put("cluster.name", "elasticsearch").build();
TransportClient client = new PreBuiltTransportClient(settings);
client.addTransportAddress(new TransportAddress(new InetSocketAddress(InetAddresses.forString("127.0.0.1"), 9300)));
--------------------------------------------------

Otherwise the parent-join module doesn't get loaded and the `has_parent` query can't be used from the transport client.

["source","java",subs="attributes,callouts,macros"]
