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 reindex is completed

We support Elasticsearch versions 1.4, 1.7, 2.4, and 5.2. The default version is 1.7. We support Elasticsearch for all environments starting with Magento Commerce (Cloud) 2.1 and later. Refer to Elasticsearch information to learn more. For Magento Commerce (Cloud) 2.0.X, you can use Solr.

Add Elasticsearch in services.yaml and .magento.app.yaml

To enable Elasticsearch, add the following code with your installed version and allocated disk space in MB to .magento/services.yaml.

elasticsearch:
   type: elasticsearch:1.7
   disk: 1024

To configure the relationships for the environment variable, set a relationship in your .magento.app.yaml in the Git branch. For example:

relationships:
    elasticsearch: "elasticsearch:elasticsearch"

Merge and deploy the code to set the configurations for Elasticsearch. For information on how these changes affect your environments, see services.yaml.

Add Elasticsearch plugins

Optionally, you can add the plugins through the .magento/services.yaml file. For example, to enable ICU analysis plugin and Python script support plugins, add the configuration plugins section with the listed plugin codes:

elasticsearch:
   type: elasticsearch:1.7
   disk: 1024
   configuration:
    plugins:
      - analysis-icu
      - lang-python

For example, if you are using Smile ElasticSuite, you should add the following plugins:

elasticsearch:
   type: elasticsearch:2.4
   disk: 1024
   configuration:
    plugins:
      - analysis-icu
      - analysis-phonetic

The following are supported Elasticsearch plugins for version 2.4:

• analysis-icu: ICU Analysis Plugin, Support ICU Unicode text analysis
• analysis-kuromoji: Japanese (kuromoji) Analysis Plugin, Japanese language support
• analysis-phonetic: Phonetic Analysis Plugin, Phonetic analysis
• analysis-smartcn: Smart Chinese Analysis Plugins
• analysis-stempel: Stempel Polish Analysis Plugin
• cloud-aws: AWS Cloud Plugin, allows storing indices on AWS S3
• cloud-azure: Azure Cloud Plugin
• cloud-gce: GCE Cloud Plugin
• delete-by-query: Support for deleting documents matching a given query
• discovery-multicast: Ability to form a cluster using TCP/IP multicast messages
• lang-javascript: Javascript language plugin, allows the use of Javascript in Elasticsearch scripts
• lang-python: Python language plugin, allows the use of Python in Elasticsearch scripts
• mapper-attachments: Mapper attachments plugin for indexing common file types
• mapper-murmur3: Murmur3 mapper plugin for computing hashes at index-time
• mapper-size: Size mapper plugin, enables the _size meta field

If using Smile ElasticSuite, the required plugins are analysis-icu and analysis-phonetic. Make sure to add these to the plugins section of services.yaml. See Add Elasticsearch plugins.

For full documentation on these plugins, see Elasticsearch plugin documentation.

Verify environment-related relationships

We use the Magento Commerce (Cloud) environment variable $MAGENTO_CLOUD_RELATIONSHIPS, a JSON object, to retrieve environment-related relationships.

To verify this information used for configurations and settings:

1. SSH into the Integration environment with Elasticsearch installed and configured.

2. Enter the following command to pretty-print connection information for Elasticsearch. You will use this information when configuring Elasticsearch through the Magento Admin.

    php -r 'print_r(json_decode(base64_decode($_ENV["MAGENTO_CLOUD_RELATIONSHIPS"])));'
   

The response includes all relationships for services and configuration data for that environment. In the response, you will locate data similar to the following for Elasticsearch:

"elasticsearch" : [
      {
         "host" : "elasticsearch.internal",
         "ip" : "250.0.97.96",
         "scheme" : "http",
         "port" : "9200"
      }
   ],

Configure Elasticsearch for your site

The last step is to configure Elasticsearch for your catalog search options through the Magento Admin. You will need the information from the variable MAGENTO_CLOUD_RELATIONSHIPS. See Configure Magento to use Elasticsearch to complete your Admin configurations.
