Catalog Search reindex fails in Adobe Commerce

Last update: July 13, 2026

Catalog Search reindexing fails in Adobe Commerce, leaving the catalogsearch_fulltext indexer in a Reindex Required or stalled state. Search results don’t reflect recent catalog updates, and indexing operations return OpenSearch-related errors. To fix this issue, verify the indexer status, confirm the OpenSearch configuration, and validate cron jobs before rerunning the Catalog Search index.

Description description

Environment

  • Adobe Commerce 2.4.x
  • Adobe Commerce on Cloud Infrastructure
  • OpenSearch

Issue/Symptoms

  • Catalog Search remains in a Reindex Requiredstate after indexing attempts.
  • The catalogsearch_fulltext indexer fails to complete reindexing operations.
  • Search results do not reflect recent catalog updates or remain incomplete.
  • Indexing operations return errors such asIndex is locked by another process, Fail in child process, or circuit_breaking_exception.
  • Search functionality becomes unavaliable after catlog updates

Cause

Catalog Search reindexing fails when Adobe Commerce can’t complete thecatalogsearch_fulltext indexing process due to OpenSearch configuration issues, indexing locks, cron failures, OpenSearch resource constraints, or extension-related errors.

Resolution resolution

Follow these steps to resolve the issue

  1. Verify the status of the Catalog Search indexer by running bin/magento indexer:statusand reviewing the status of catalogsearch_fulltext. If the indexer shows Reindex Required, continue with the remaining troubleshooting steps.

  2. Confirm that Adobe Commerce uses OpenSearch as the search engine by running bin/magento config:show catalog/search/engine. Verify that the command returns opensearch.

  3. Run a manual reindex using bin/magento indexer:reindex catalogsearch_fulltext. After the command completes, verify that storefront search returns the expected results.

  4. Reset the Catalog Search indexer if it remains stuck or continues to report Reindex Required. Run bin/magento indexer:reset catalogsearch_fulltext, then rerun bin/magento indexer:reindex catalogsearch_fulltext.

    Note: Resetting an indexer only resets its status within Adobe Commerce. It doesn’t delete OpenSearch indexes or remove catalog data.

  5. Verify that cron jobs execute correctly by running bin/magento cron:run. Confirm that scheduled indexing processes run successfully and complete pending indexing tasks.

  6. Review the exact error message if reindexing still fails.

    • If Catalog Search remains in Reindex Required, verify cron functionality, run a manual reindex, and reset the indexer if necessary.

  7. Check whether the error message shows Index is locked by another process.

    • Verify that no indexing process is currently running.
    • Reset the affected indexer.
    • Retry the reindex.

  8. Check whether the error message shows Fail in child process.

    • Review the exception logs.
    • Verify whether OpenSearch-related errors are present.
    • This error is typically a symptom rather than the root cause of the failure.
    • Contact Adobe Support if the issue persists.

  9. Check whether the error message shows circuit_breaking_exception or [ parent] Data too large.

    • Review any available OpenSearch-related error messages.
    • Contact Adobe Support for further investigation.

  10. If search results remain incomplete after reindexing:

    • Verify the search engine configuration.
    • Verify the Catalog Search indexer status.
    • Flush caches if necessary.

  11. Do not delete OpenSearch indexes as a first troubleshooting step.

    • Adobe Commerce can recreate search indexes during a reindex operation.
    • Deleting indexes does not resolve underlying issues such as OpenSearch resource constraints, OpenSearch health issues, OpenSearch connectivity issues, or failed indexing operations.
    • If the root cause is related to OpenSearch health or infrastructure, rebuilding indexes fails for the same reason.

  12. Contact Adobe Supportif the issue continues.

    • Catalog Search reindexing consistently fails.
    • The indexer remains stuck after being reset.
    • OpenSearch-related errors appear during indexing.
    • Search functionality remains unavailable after reindexing.
    • The issue is isolated to a specific environment.
    • The root cause cannot be identified by using the troubleshooting steps above.

    Include the following information:

    • Output from bin/magento indexer:status
    • Output from bin/magento config:show catalog/search/engine
    • Relevant exception logs
    • The exact error message returned during reindexing
