Falling back to Elasticsearch7 when search engine set to Opensearch

Last update: April 22, 2024

This article provides a solution for the issue when a Falling back to Elasticsearch7 error occurs when the search engine is set to OpenSearch in Adobe Commerce.

Affected versions

Adobe Commerce on cloud infrastructure 2.4.4 - 2.4.5

NOTE
OpenSearch is available as a search engine starting from Adobe Commerce 2.4.6.

Issue

You set your search engine to OpenSearch, but see this type of error in the var/log/support_report.log file:

[2024-04-04T00:27:41.212916+00:00] report.ERROR: opensearch search engine doesn't exist. Falling back to elasticsearch7 [] []

Steps to reproduce:

  1. Verify that OpenSearch is installed by running this command: curl 127.0.0.1:9200

    If it indicates 1.2.4, then OpenSearch is already installed.
  2. Go to Stores > Configuration > Catalog > Catalog Search.
  3. Check the search engine. It will show Elasticsearch7.

Cause

Even though your version does support OpenSearch, the application will only recognize/accept Elasticsearch7 as the search engine.

Starting in Adobe Commerce version 2.4.6, the application was updated to allow OpenSearch to be selected as the search engine.
If you go to Stores > Configuration > Catalog > Catalog Search in a non-cloud environment, you will be able to change this option as shown in the Solution below.
(Note: In a cloud environment, this field can’t be changed because the search engine is locked in the app/etc/env.php file.)

Solution

Update the SEARCH_CONFIGURATION variable in the .magento.env.yaml file, and ensure that the search engine is set to elasticsearch7.

Set up OpenSearch service in the Commerce on Cloud Infrastructure guide.
