AEM repository search returns no results with DITA Map or Topic filters after migration

Last update: October 2, 2026

This article explains how to resolve an issue in Adobe Experience Manager (AEM) where repository searches with DITA Map or Topic filters return no results after migrating to a new AEM instance. The solution involves reindexing the damAssetLucene index.

Description description

Environment

  • Adobe Experience Manager 6.5 LTS on-premises
  • AEM Guides DITA Map and Topic repository search
  • AEM Assets repository indexed by damAssetLucene

Issue/Symptoms

  • After you migrate to a new AEM instance, repository searches with DITA Map or DITA Topic filters return no results.
  • Searches without those filters return results as expected.
  • The issue affects the environments migrated with the new instance.
  • No specific error message is displayed.

Cause

In the reported migration scenario, the damAssetLucene index is stale or incomplete, so filtered repository searches don’t return the expected results. Reindexing can address this condition when the index state confirms that it is needed.

Resolution resolution

Follow the steps below to resolve the issue:

  1. Sign in to the AEM Author instance as an administrator.

  2. Check the damAssetLucene index status in the Oak Index Manager or its IndexStats MBean. For the MBean, use the JMX URL pattern http://<host>:<port>/system/console/jmx/compositeData/org.apache.jackrabbit.oak%3Aname%3DdamAssetLucene%2Ctype%3DIndexStats. Replace <host> and <port> with your AEM instance values.

  3. Before reindexing, confirm that the damAssetLucene index is stale or incomplete and that the repository search query and DITA filters are correct.

  4. If the index state confirms that reindexing is needed, set the reindex property for /oak:index/damAssetLucene to true in CRX/DE Lite:

    • Open CRX/DE Lite at http://<host>:<port>/crx/de.
    • Browse to /oak:index/damAssetLucene.
    • Set the Boolean reindex property to true.
    • Save the change.

    Note: Reindexing traverses repository content and can take several hours or longer, depending on repository size. It can consume significant resources; perform it during a low-activity or approved maintenance period.

  5. Monitor the index status in the Oak Index Manager or IndexStats MBean. Confirm that reindexing completes and the reindex property returns to false.

  6. After reindexing completes, test repository searches with DITA Map and DITA Topic filters enabled and disabled. Confirm that filtered searches return the expected results and unfiltered searches continue to work.

  7. Repeat the index-state check, reindexing, monitoring, and search validation for each other affected AEM environment.
