==== 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 InetSocketTransportAddress(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.
