# Subscribe and unsubscribe

Available in Classic

Once you have reviewed the Search Engine Service's required specifications and fully understood the [Usage scenario](/docs/en/ses-procedure) and [Glossary](/docs/en/ses-glossary), you are ready to begin using the Search Engine Service. The first thing to do now is to request a subscription for the Search Engine Service.

## Request subscription

There is no separate subscription process for the Search Engine Service. If you have created a cluster, you have already requested a subscription.

- New clusters cannot be created in a classic environment after July 21, 2022. Use a VPC environment. For information on how to create a cluster in a VPC environment, see [Create cluster](/docs/en/ses-cluster-vpc#%ED%81%B4%EB%9F%AC%EC%8A%A4%ED%84%B0%EC%83%9D%EC%84%B1).

### Next stage

You have completed all of the starter courses to use the Search Engine Service. Learn how to use the various features provided by the Search Engine Service by reading the Search Engine Service user guide.

- Recommended path
  - To review your understanding of the Search Engine Service: go to [Search Engine Service glossary](/docs/en/ses-glossary)
  - To review the entire sequence of using the Search Engine Service: go to [Search Engine Service scenarios](/docs/en/ses-procedure)
  - To set permissions for the Search Engine Service: go to [Managing Search Engine Service permissions](/docs/en/ses-subaccount-classic)

## Cancel subscription

There is no separate procedure for canceling the Search Engine Service. Once you've stopped using created clusters and deleted all of them, then you can consider the service as being canceled. For how to delete a cluster, see [Delete cluster](/docs/en/ses-cluster-classic#%ED%81%B4%EB%9F%AC%EC%8A%A4%ED%84%B0%EC%82%AD%EC%A0%9C).
