There are more AWS SDK examples available in the AWS Doc SDK Examples GitHub repo.
Code examples for OpenSearch Service using AWS SDKs
The following code examples show you how to use Amazon OpenSearch Service with an AWS software development kit (SDK).
Basics are code examples that show you how to perform the essential operations within a service.
Actions are code excerpts from larger programs and must be run in context. While actions show you how to call individual service functions, you can see actions in context in their related scenarios.
Get started
The following code example shows how to get started using OpenSearch Service.
- Java
