This plugin adds full-text search capabilities to your Elgg installation, allowing you to search through entities and annotations (in ELGG 1.8).

1. Install the plugin (and it's dependencies) by running:

    composer require pleio/elasticsearch
   

2. Add the following configuration to engine/settings.php:

    $CONFIG->elasticsearch = array(
        'hosts' => array(
            '127.0.0.1'
        )
    );
   
    $CONFIG->elasticsearch_index = 'pleio-dev';
   

3. Activate the plugin through the Elgg admin panel.

4. Create the index and mappings in Elasticsearch by running:

    php console.php es:index:reset
   

This command will (re-)create the index. All existing content attached to the Elasticsearch will be deleted. From now on all entity CRUD actions will automatically be synced with Elasticsearch.

The tool comes with a tool to synchronize all existing content with Elasticsearch. Run

php console.php es:sync:all

to start a bulk synchronisation.

It is also possible to use this tool in conjunction with PleioAsyncTaskHandler and tika-server to search through ElggFile contents.

1. Download and run the tika-server:

    wget http://www.apache.org/dyn/closer.cgi/tika/tika-server-1.15.jar
    java -jar tika-server-1.15.jar
   

2. Add the following configuration to engine/settings.php:

    $CONFIG->tika_server = ["localhost", 9998];
   

3. Make sure the PleioAsyncTaskHandler is running by:

    php console.php async:taskhandler
   

Now when files are added or updated, the contents are indexed automatically.
