Set up Elasticsearch service

Elasticsearch is an open source product that enables you to take data from any source, any format, and search and visualize it in real time.

  • Elasticsearch performs quick and advanced searches on products in the product catalog
  • Elasticsearch Analyzers support multiple languages
  • Supports stop words and synonyms
  • Indexing does not impact customers until the reindex operation completes

You can use the following instructions for service setup on Magento Commerce Cloud Pro Integration environments and Starter environments, including master branch. You must submit a support ticket to configure the service on Pro Production and Staging environments. See Services.

Magento recommends that you always set up Elasticsearch for your Magento Commerce Cloud project even if you plan to configure a third-party search tool for your Magento Commerce application. Setting up Elasticsearch provides a fallback option in the event that the third-party search tool fails.

To enable Elasticsearch:

  1. Add the elasticsearch service to the .magento/services.yaml file with the Elasticsearch version and allocated disk space in MB.

    1
    2
    3
    
    elasticsearch:
        type: elasticsearch:<version>
        disk: 1024
    

    For details on determining the correct version to install, see Elasticsearch software compatibility.

  2. Set the relationships property in the .magento.app.yaml file.

    1
    2
    
    relationships:
        elasticsearch: "elasticsearch:elasticsearch"
    
  3. Add, commit, and push code changes.

    1
    
    git add -A && git commit -m "Enable Elasticsearch" && git push origin <branch-name>
    

    For information on how these changes affect your environments, see Services.

  4. Verify the service relationships and configure Elasticsearch in the Admin UI.

  5. Reindex the Catalog Search index.

    1
    
    bin/magento indexer:reindex catalogsearch_fulltext
    
  6. Clean the cache.

    1
    
    bin/magento cache:clean
    

Elasticsearch software compatibility

When you install or upgrade your Magento Commerce Cloud project, always check for compatibility between the Elasticsearch service version and the Elasticsearch PHP client for Magento Commerce.

  • First time setup–Confirm that the Elasticsearch version specified in the services.yaml file is compatible with the Elasticsearch PHP client configured for Magento Commerce.

  • Project upgrade–Verify that the Elasticsearch PHP client in the new Magento version is compatible with the Elasticsearch service version installed on the Cloud infrastructure.

The following table lists compatible versions of the Elasticsearch software supported by Magento Commerce.

Elasticsearch service Elasticsearch composer package Status
1.7 – 2.4.x 2.x.x deprecated
5.2.x 5.x.x default versions for Magento Commerce versions 2.2.x - 2.2.7 and 2.3.0
6.x 6.x recommended, default versions for Magento Commerce versions 2.2.8 and 2.3.1 and later.

To check Elasticsearch software compatibility:

  1. Use SSH to log in to the remote environment.

  2. Check the Composer package version for elasticsearch/elasticsearch.

    1
    
    composer show elasticsearch/elasticsearch
    

    In the response, check the installed version in the versions property.

    Also, you can find the Elasticsearch PHP client version in the composer.lock file in the environment root directory.

  3. From the command line, retrieve the Elasticsearch service connection details.

    1
    
    vendor/bin/ece-tools env:config:show services
    

    In the response, find the IP address for the Elasticsearch service endpoint:

       "version" : {
         "number" : "6.5.4",
         "build_flavor" : "default",
         "build_type" : "deb",

         "minimum_index_compatibility_version" : "5.0.0"
    },
    "  tagline" : "You Know, for Search"
    }
    
  5. Check version compatibility between the Elasticsearch service and the PHP client.

    If the versions are incompatible, make one of the following updates to your environment configuration:

    • Change the Elasticsearch service version in the services.yaml file to a version that is compatible with the Elasticsearch PHP client. On Pro Staging and Production environments, you must submit a support ticket to change the Elasticsearch service version.

    • Change the Elasticsearch PHP client to a version that is compatible with the Elasticsearch service version.

Restart the Elasticsearch service

If you need to restart the Elasticsearch service, you must contact Magento support.

Additional search configuration

  • By default, the search configuration for Cloud environments regenerates each time you deploy. You can use the SEARCH_CONFIGURATION deploy variable to retain custom search settings between deployments. See Deploy variables.

  • Magento Commerce Cloud projects provisioned with a shared Production and Staging environment use a single Elasticsearch instance, so you must specify a unique Elasticsearch Index prefix for each of these environments. See Configure Magento to use Elasticsearch in the Configuration Guide.

  • After you set up the Elasticsearch service for your project, use the Magento Admin UI to test the Elasticsearch connection and customize Elasticsearch settings for Magento Commerce.

Elasticsearch plugins

Optionally, you can add Elasticsearch plugins by adding the configuration:plugins section to the .magento/services.yaml file. For example, the following code enables the ICU analysis plugin and Python script support plugins.

1

elasticsearch:
    type: elasticsearch:<service-version>
    disk: 1024
    configuration:
        plugins:
            - analysis-icu
            - lang-python

If you use the ElasticSuite third-party plugin, you must update the ece-tools package to version 2002.0.19 or later.
