Configuring the Elasticsearch plugin

You can configure the Elasticsearch plugin from the Craft Control Panel (some settings only), of from the config/elasticsearch.php file in your Craft installation (all settings). If a setting is defined both in the CP and in the configuration file, the latter takes precedence.

The src/config.php, file is a configuration template to be copied to config/elasticsearch.php.

💡 If you currently don't have an Elasticsearch server handy, here's how you can set one up.

In both the configuration file and the CP


Type: string

The Elasticsearch instance endpoint URL (with protocol, host and port). Ignored if elasticsearchComponentConfig is set.


Type: bool

A boolean indicating whether authentication is required on the Elasticsearch instance.
Ignored if elasticsearchComponentConfig is set.


Type: string

The username used to authenticate on the Elasticsearch instance if it's protected by X-Pack Security.
Ignored if isAuthEnabled is set to false or elasticsearchComponentConfig is set.


Type: string

The password used to authenticate on the Elasticsearch instance if it's protected by X-Pack Security.
Ignored if isAuthEnabled is set to false or elasticsearchComponentConfig is set.


Type: array

The elasticsearch configuration used to highlight query results. Only pre_tags and post_tags are configurable in the CP, advanced config must be done in the file.
For more options, refer to the elasticsearch documentation.


Type: int[]

An array of entry type ids of which entries should not be indexed.

Only in the configuration file


Type: string[]

An array of IP addresses allowed to use the Elasticsearch console commands.


Type: string[]

An array of hostnames allowed to use the Elasticsearch console commands.


Type: callable

A callback (function(string $entryContent): string) used to extract the content to be indexed from the full HTML source of the entry's page.

The default is to extract the HTML code between those 2 comments: <!-- BEGIN elasticsearch indexed content --> and <!-- END elasticsearch indexed content -->.


Type: array

An associative array passed to the yii2-elasticsearch component Connection class constructor.
All public properties of the yii2-elasticsearch component Connection class can be set.
If this is set, the elasticsearchEndpoint, username, password and isAuthEnabled settings will be ignored.

Indexable content

By default, the content indexed in each entry is between the <!-- BEGIN elasticsearch indexed content --> and <!-- END elasticsearch indexed content --> HTML comments in the source of the entry page.

If you're using semantic HTML in your templates, then putting your <main> or <article> element between those comments should be ideal.

If you need more control over what is indexed, you'll have to set up a custom contentExtractorCallback.

Running a search

The search feature can be used from a frontend template file by calling the'Something to search') variable. For instance, in a template search/index.twig:

{% set results ='q')) %}

{% block content %}
    <h1>{{ "Search"|t }}</h1>

    <form action="{{ url('search') }}">
        <input type="search" name="q" placeholder="Search" value="{{'q') }}">
        <input type="submit" value="Go">

    {% if results|length %}
        <h2>{{ "Results"|t }}</h2>

        {% for result in results %}
            <h3>{{ result.title }}</h3>
                <small><a href="{{ result.url|raw }}">{{ result.url }}</a><br/>
                    {% if result.highlights|length %}
                        {% for highligh in result.highlights %}
                            {{ highligh|raw }}<br/>
                        {% endfor %}
                    {% endif %}
        {% endfor %}
    {% else %}
        {% if'q') is not null %}
                <em>{{ "No results"|t }}</em>
        {% endif %}
    {% endif %}
{% endblock %}

Each entry consists of the following attributes:

  • id: unique ID of the result
  • title: page title
  • url: full url to the page
  • score: entry result score
  • highlights: array of highlighted content matching the query terms

Auto indexing

The plugin automatically indexes entries (created, updated or removed), as long as they're not in a blacklisted entry types, or disabled.

All entries are reindexed (in the background) when plugin settings are saved.

Elasticsearch plugin utilities

If your Elasticsearch index becomes out of sync with your sites contents, you can go to Utilities → Elasticsearch then click the Reindex all button.

Elasticsearch plugin console commands

The plugin provides an extension to the Craft console command that lets you reindex all entries or recreate empty indexes.

Recreate empty indexes

Remove index & create an empty one for all sites

./craft elasticsearch/elasticsearch/recreate-empty-indexes

Reindex all sites

./craft elasticsearch/elasticsearch/reindex-all

About yii2-elasticsearch library

At the time of the release of this plugin, no stable 2.1 version of the yiisoft/yii2-elasticsearch was released yet. However, that version is mandatory in order to connect to Elasticsearch instances 5 or upper.

To simplify the installation process, a la-haute-societe/yii2-elasticsearch fork was made and flagged as stable. Please, note that this fork was tested and intended to work with this plugin only.


This plugin is free to try in development environments, but requires payment to be used in production environments. The license fee for this plugin is $99 (license + one year of updates) via the Craft Plugin Store, then $29 per year for updates (optional).

Elasticsearch plugin Roadmap

  • Handle dependencies update
  • Detect need for re-indexation
  • Switch form la-haute-societe/yii2-elasticsearch to official 2.1 yiisoft/yii2-elasticsearch library as soon as a stable version will be released
