I am trying to use Aggregation API and for that documentation tells me to use
```auto
SearchResponse sr = node.client().prepareSearch()
.setQuery( /* your query */ )
.addAggregation( /* add an aggregation */ )
.execute().actionGet();
```
But it does not tell me how to get the client object node.client()
RestHighLevelClient does not have a prepareSearch() method in 7.9.0. Then I tried upgrading to 7.12.1 but then I cannot find the class
org.elasticsearch.client.RestHighLevelClient
at all. I am really confused. Am I missing a library? I am using two dependencies:
```auto
org.elasticsearch
elasticsearch
7.9.0
org.elasticsearch.client
elasticsearch-rest-high-level-client
7.9.0
```
Also, the current documentation, e.g. [Aggregations | Java API (deprecated) [7.12] | Elastic](https://www.elastic.co/guide/en/elasticsearch/client/java-api/current/java-aggs.html), states that the doc is deprecated. Another very confusing thing. Can anybody shed some light on this?

Welcome!
The TransportClient is indeed deprecated. So you should look at the rest client documentation.
> **[Java REST Client \[7.12\] | Elastic](https://www.elastic.co/guide/en/elasticsearch/client/java-rest/current/index.html)**
Specifically [Search API | Java REST Client [7.12] | Elastic](https://www.elastic.co/guide/en/elasticsearch/client/java-rest/current/java-rest-high-search.html)
I'm also sharing some few examples at:

What does the RestHighLevelClient class have to do with TransportCLient?
In your example you are using RestHighLevelClient...

Yes. That's the way to go.
