Install Elasticsearch

Download and install Elasticsearch

Install Elasticsearch on your server. As an example, use the following Docker command:

1
docker run -d --name ibexa-dxp-elasticsearch -p 9200:9200 -p 9300:9300 -e "discovery.type=single-node" docker.elastic.co/elasticsearch/elasticsearch:7.16.2

Note

Ibexa DXP supports Elasticsearch in version 7.16.2 or higher.

Verify the instance

To make sure that the Elasticsearch instance operates properly, access the instance (for example, with curl http://localhost:9200/).

If Elasticsearch operates properly, an object with cluster details is displayed. It should be similar to the following example:

        "minimum_wire_compatibility_version" : "6.8.0",
        "minimum_index_compatibility_version" : "6.0.0-beta1"
    },
    "tagline" : "You Know, for Search"
}

Set the default search engine

Set the following environment variable (for example, in the .env or .env.local file):

1
SEARCH_ENGINE=elasticsearch

Configure the search engine

Ibexa DXP comes pre-configured to work with an Elasticsearch cluster that uses default settings, and you can use this initial setup for testing purposes. However, to effectively search through actual data, you must provide specific settings. All configuration is made in the /config/packages/ibexa_elasticsearch.yaml file.

Note

All the settings, their order and meaning, correspond to the settings that are described in the Elasticsearch documentation.

First, decide how Ibexa DXP connects to Elasticsearch and configure other connection settings.

For more information, see Configuring connections.

Then, define a field type mappings template that instructs Elasticsearch to interpret Ibexa DXP fields as specific types.

For more information, see Configuring field type mappings.

Push the templates

For each of your defined connections, push the templates to the Elasticsearch engine by running the following command:

1
php bin/console ibexa:elasticsearch:put-index-template

You can modify the behavior of the command with a number of switches. Use the -h switch to display a complete list of available options.

Reindex the database

After creating index templates, run the following command to reindex your data:

1
php bin/console ibexa:reindex

Risks of premature indexing

Don't reindex your data before you create index templates. Otherwise Elasticsearch attempts to use its dynamic field mapping feature to create type mappings automatically.
