AEM reindexing with OAK Index

Reindexing in AEM (Adobe Experience Manager) using the OAK indexing system is crucial for maintaining performance and ensuring that content is searchable. This tutorial will guide you through the process of reindexing in AEM 6.5 using OAK indexes.

Understanding OAK Indexes

OAK is the underlying storage mechanism for AEM, and it uses indexes to improve the performance of queries. When content is added, modified, or deleted, the indexes need to be updated to reflect these changes. Reindexing is necessary when the index becomes stale or when the structure of the content changes significantly.

Step 1: Access AEM Web Console

a) Log in to AEM: Open your web browser and log in to your AEM instance.

b) Navigate to the Web Console: Access the OAK index management console by going to:

http://<your-aem-instance>:<port>/system/console

Replace <your-aem-instance> and <port> with your AEM instance details.

Step 2: Locate the Indexes

a) Go to the Lucene Indexes: In the web console, navigate to:

http://<your-aem-instance>:<port>/system/console/jcr/indices

b) View Existing Indexes: You will see a list of existing indexes. Each index is associated with a specific type of content or query.

Step 3: Reindexing an OAK Index

a) Select the Index to Reindex: Click on the index you want to reindex. This will take you to the index configuration page.

b) Reindex the Selected Index: Look for the option to reindex. This is usually a button labeled "Reindex" or "Rebuild". Click this button to start the reindexing process.

c) Monitor the Progress: Depending on the size of your content repository, the reindexing process may take some time. Monitor the progress in the console.

Step 4: Verify the Reindexing

a) Check the Index Status: After the reindexing process is complete, check the status of the index to ensure it is up-to-date.

b) Test Queries: Perform some test queries to verify that the content is being returned correctly and that the performance has improved.

Step 5: Troubleshooting

If you encounter issues during the reindexing process, consider the following:

Check Logs: Review the AEM error logs for any messages related to indexing. This can provide insight into what went wrong.

Configuration Issues: Ensure that the index configuration is correct. Misconfigured indexes can lead to performance issues.

Resource Availability: Ensure that your AEM instance has sufficient resources (CPU, memory) available during the reindexing process.

Conclusion

Reindexing in AEM 6.5 using OAK indexes is a straightforward process that helps maintain the performance and accuracy of your content repository. Regularly reindexing can prevent issues related to stale indexes and ensure that your content remains searchable and performant. Always monitor the process and verify the results to ensure a smooth experience for your users.
