Kendra search errors.

Amazon Kendra search errors can occur for various reasons, affecting the performance and accuracy of your search queries. Here are some common causes and steps to address Kendra's search errors:

1. Check Query Syntax:
   • Review the syntax of your search queries to ensure they are correctly formatted and comply with Kendra's query language.
2. Verify Index Status:
   • Navigate to the Amazon Kendra console and review the status of your index. Ensure it's in an active and healthy state.
3. Monitor Query Latency:
   • Keep an eye on the latency of your search queries. If there's a sudden increase in latency, it might indicate issues with the index or search service.
4. Inspect Indexing Frequency:
   • Ensure that the data sources feeding into your Kendra index are set up to synchronize at an appropriate frequency. Stale data can affect search results.
5. Review Data Source Configurations:
   • Verify that the data sources are correctly configured and that Kendra has the necessary permissions to access them.
6. Check for Missing or Incomplete Data:
   • Confirm that the data in your index is complete and doesn't have any missing fields or records.
7. Monitor for AWS Service Health Issues:
   • Check the AWS Service Health Dashboard for any reported issues with the Kendra service.
8. Inspect Query Results:
   • Review the results returned by Kendra for specific queries to identify any discrepancies or unexpected outcomes.
9. Verify IAM Roles and Policies:
   • Confirm that the IAM roles associated with your Kendra resources have the necessary permissions to access datasets, indexes, and other resources.
10. Regularly Review Query Performance:
    • Periodically review query performance metrics to identify any trends or anomalies that might indicate issues.
11. Inspect Kendra Logs:
    • Access the logs generated by Kendra to look for error messages, warnings, or any other information that might provide insights into the cause of the errors.
12. Set Up CloudWatch Alarms:
    • Create CloudWatch Alarms to be notified of critical metrics related to your Kendra index and search service.
13. Check for Query Complexity:
    • If your queries are complex, consider breaking them down into simpler queries to pinpoint the issue.
14. Contact AWS Support:
    • If you've gone through these steps and are still experiencing search errors, consider reaching out to AWS Support for further assistance.
