Elasticsearch Grails plugin

Documentation about the plugin

How can I obtain the plugin?

Just like any other Grails plugin, through the Grails Plugin center. Edit your project’s build.gradle file, by adding the plugin’s dependency declaration:

build.gradle:

dependencies {
    ...
    implementation "org.grails.plugins:elasticsearch:5.0.0-RC1"
    ...
}

Versioning

In order to simply the versioning, with v3.0.0.M1 the Elasticsearch Grails plugin is using Semantic Versioning 2.0.0. To understand what that means, please see the specification documentation.

The plugin version is neither tied to the Grails release nor the Elasticsearch client API used. Often it is possible to connect to newer Elasticsearch servers if you do not require the new features.

Plugin Version	Grails Version	Elasticsearch Client API Version
5.0.0	7.x	7.17.29
4.0.0	5.3.x - 6.x.x	7.17.29
3.0.0	4.0.x - 6.x.x	7.8.0
2.7.0	3.3.x	7.3.0
2.5.0	3.3.x	5.5.3
2.4.2	3.3.y	5.4.3
2.4.1	3.3.x	5.4.3
2.4.0	3.3.y	5.4.3
1.4.1	3.1.y	5.4.1
1.2.1	3.2.y	2.3.z
1.2.0	3.1.y	2.3.z
1.0.0.x	3.1.y	1.6.z
0.1.0.x	2.y	2.1.z
0.0.4.x	2.y	1.6.z

Example Configuration for Grails 7

In the following we demonstrate two example configurations using Hibernate or MongoDB as a datastore.

Hibernate

Check out the example application in this repository on using Elasticsearch in Grails 7.x with Hibernate.

Add the following to your grails-app/conf/application.yml:

elasticSearch:
    plugin:
        mapperAttachment:
            enabled: false
    client:
        mode: transport
        hosts:
        - {host: localhost, port: 9200}
    cluster.name: elasticsearch
    bulkIndexOnStartup: true
    datastoreImpl: hibernateDatastore

MongoDB

build.gradle:

dependencies {
  compile 'org.grails.plugins:mongodb:7.0.0'
}

grails-app/conf/application.yml:

elasticSearch:
    plugin:
        mapperAttachment:
            enabled: false
    client:
        mode: transport
        hosts:
        - {host: localhost, port: 9200}
    cluster.name: elasticsearch
    bulkIndexOnStartup: true
    datastoreImpl: mongoDatastore

NOTE

This project is a fork based on the great work done by the guys at:

• https://github.com/mstein/elasticsearch-grails-plugin

• https://github.com/noamt/elasticsearch-grails-plugin

Why would you want to fork the original Elasticsearch plugin?

The original Elasticsearch plugin relies on Hibernate-specific GORM components, thus rendering it unusable if you back your Grails application by any other database.

Here, have a yak:
