Detailed Explanation:

The Elasticsearch REST High Level Client simplifies interaction with Elasticsearch. Here's how to perform basic CRUD (Create, Read, Update, Delete) operations:

1. Setting up the Environment:

• Dependencies: Ensure you have the necessary Elasticsearch Java client dependency in your pom.xml (for Maven) or build.gradle (for Gradle). For example, in Maven:

<dependency>
    <groupId>org.elasticsearch.client</groupId>
    <artifactId>elasticsearch-rest-high-level-client</artifactId>
    <version>8.11.2</version> 
</dependency>

• Configuration: Create an instance of RestClientBuilder to configure the connection to your Elasticsearch cluster. Specify the hosts (IP addresses and ports) of your Elasticsearch nodes.

RestClientBuilder builder = RestClient.builder(
        new HttpHost("localhost", 9200, "http"));

2. Create (POST):

This creates a new document in a specified index.

RestHighLevelClient client = new RestHighLevelClient(builder);
IndexRequest request = new IndexRequest("my-index").id("1").source(jsonBuilder().startObject()
        .field("name", "John Doe")
        .field("age", 30)
        .endObject());
IndexResponse response = client.index(request, RequestOptions.DEFAULT);
System.out.println("Index Response ID:" + response.getId());
client.close();

Replace "my-index", "1", and the fields with your values. jsonBuilder() comes from org.elasticsearch.common.xcontent.XContentBuilder.

3. Read (GET):

Retrieves a specific document by ID.

GetRequest request = new GetRequest("my-index", "1");
GetResponse response = client.get(request, RequestOptions.DEFAULT);
System.out.println(response.getSourceAsString());
client.close();

4. Update (POST):

Updates a document. Use an UpdateRequest with doc() to specify the fields to modify.

UpdateRequest request = new UpdateRequest("my-index", "1").doc(jsonBuilder().startObject().field("age", 35).endObject());
UpdateResponse response = client.update(request, RequestOptions.DEFAULT);
client.close();

5. Delete (DELETE):

Removes a document by ID.

DeleteRequest request = new DeleteRequest("my-index", "1");
DeleteResponse response = client.delete(request, RequestOptions.DEFAULT);
client.close();

Important Notes:

• Replace placeholders like "my-index" and "1" with your actual index and document ID.
• Handle exceptions appropriately (e.g., IOException, ElasticsearchException).
• Always close the RestHighLevelClient using client.close() to release resources.
• Remember to manage your index mappings appropriately.
