index_not_found_exception Elasticsearch Magento 2 | Resolved

If you have been coming across the index_not_found_exception error in Elasticsearch, you have come to the right place. According to our experts, this error often occurs when we try to perform an operation on an index that doesn’t exist.

In Magento 2, Elasticsearch works as a search engine to improve the performance of the product search and catalog browsing features.

Interestingly, the index_not_found_exception in Magento 2 indicates a problem with the Elasticsearch configuration or connection. For instance, the index may have been deleted or renamed, or there could be a network issue preventing Magento from connecting to Elasticsearch.

Troubleshooting Tips

Here are a few troubleshooting tips to help resolve the issue:

• First, check the Elasticsearch service is running with the following command:

  sudo service elasticsearch status

  In case it is not running, our experts recommend running this command:

  sudo service elasticsearch start
• Next, we have to verify the Elasticsearch configuration in Magento 2 Admin. We can locate the file at app/etc/env.php.

  Here, we have to check the elasticsearch7_index_prefix value is the same as the index name in Elasticsearch.
• After that, ensure the  Elasticsearch index exists with this command:

  curl -X GET "localhost:9200/_cat/indices?v"

  In case the index does not exist, we can create it as seen below:

  curl -X PUT "localhost:9200/magento2_index_name"

  Remember to replace magento2_index_name with the name of the index that Magento 2 is trying to access.
• Finally, try clearing the Magento 2 cache as seen below:

  bin/magento cache:clean
